Aggregate Blending, Absorption & Specific Gravity 15 Fine Aggregate Specific Gravity • ASTM C128 – Dry aggregate – Soak in water for 24 hours – Spread out and dry to SSD – Add 500 g of SSD aggregate to pycnometer of known volume • Pre-filled with some water – Add more water and agitate until air bubbles have been removed It must be free from veins, adherent coatings and injurious amounts of disintegrated pieces, alkali, vegetable matter and other deleterious substances. It is described as Broken stone ballast; Dry well shaken=1600—1870 kg/cum; Perfectly wet =1920—2240 kg/cum; Shingles 3-38mm=1460 kg/cum; Gravel; Loose = 1600 kg/ cum; Un disturbed =1920-2160 kg/cum; Riprap =1280—1440 kg/cum; Granite = 2630—2760 kg/cum; Brick Ballast = 1200 kg/ cum; i hope you understand In addition, it calculates the total weight if you know the density of the crushed material. Maximum aggregate size can affect HMA, PCC and base/subbase courses in several ways. If a statement is like: A coarse aggregates with higher bulk density, then it means few of the voids can be filled by using fine aggregates and cement. ANDI stands for Aggregate Nutrient Density Index, a scoring system that rates foods on a scale from 1 to 1000 based on nutrient content. Relative Density or Specific Gravity of Aggregate. Aggregate Contains both permeable and impermeable pores. Multiply Square Feet by the Depth * = Cubic Feet. Proper selection and grading of aggregates are important consideration, both economically as well as technically. For structural concrete common material like gravel and crushed stone are used. REFERENCE ITEMS (210) Go to Top. The approximate value of bulk density for aggregate usually used for normal-weight concrete varies between, Most of the aggregates possess a relative density within. Density, also known as the unit weight, is the mass per unit volume of the material. Following are the density of coarse aggregate. Based on their size, the aggregates are named as: The material below 4.75 mm size refers to fine aggregate. River gravels make the best coarse aggregate. Construction aggregates are extracted from natural sand and gravel deposits or quarried from rock formations. You will need: 24.93 bulk bags of this aggregate type. The density of Cement, Sand and Aggregate, Relative Density or Specific Gravity of Aggregate, Density of Building Materials As Per IS 875 Part-1. It is described as, Absolute Specific Gravity = (Weight of oven-dried aggregate at 100°c for 24 hours) / (Weight of water’s volume equal to that of aggregate’s solids excluding pores), The absolute specific gravity is usually not needed in concrete technology. Some of natural commercially used aggregates are as follows: 1. Figure 3.4 Schematic of Dry Lightweight Aggregate 3.5 Aggregate Bulk Density Aggregate bulk density is defined as the ratio of the mass of a given quantity of material and the total volume occupied by it.

Grading should be according to the table as given below: Following are the density of coarse aggregate, Density of Cement    Ordinary Portland cement=1440kg/cum    Rapid Hardening cement =1350kg/ cum Bulk density of coarse aggregate=1600 to 1800 kg/ cum, Granite                  = 2630—2760 kg/cum. These mining operations produce some 2.5 billion tons of construction aggregates annually for the U.S. domestic market. The specific gravity of aggregate excluding all pores is referred to as the absolute specific gravity. Save my name, email, and website in this browser for the next time I comment. Stone ballast or stone metal is important material used in construction of building and roads. Aggregate which occupy nearly 80 to 85 % volume of concrete are most important part of the concrete or RCC. The raw, mined materials are crushed to suitable sizes if required, then sorted by size and shape for use as fine or coarse fractions. Aggregate Density Table, free PDF download. Next, the tube was gently inverted several times. The normal weight of stone aggregate in loose state is= 1400 to 1600 kg per cum, but for illustration an average value 1500 kg per cum is considered. gradation for compaction control of aggregate materials in the field to avoid inadequate compaction. Properties, advantages, Disadvantages. density of gravel, Pea is equal to 1 788 kg/m³.In Imperial or US customary measurement system, the density is equal to 111.62 pound per cubic foot [lb/ft³], or 1.03 ounce per cubic inch [oz/inch³] . 2. *Please note this tool is intended to be a guide only as the exact conversion depends on a number of factors beyond our control, for example the bulk density of the aggregate, moisture, method and degree of compaction, type of sub-base etc. When sand is packed, sand particles are forced to form narrow disposition, resulting in more material in the volume. The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m 3 (75-110 lb/ft 3). If only permeable pores are considered, and the material’s solid volume is excluded, then the resulting specific gravity refers to apparent specific gravity. This volume includes the voids between, as well as the pores within the particles. Only cement is unusually used; it is used to bind coarse and fine aggregate to produce mortar and concrete. First choose which product you are going to use: 10mm & 20mm Gravel 40mm MOT, DOT and 40mm & 75mm Crusher Runs Sharp Sand Ballast 40mm & 75mm Clean Stone Recycled Crushed Brick & Concrete (6F5/6F2) Also Read – Difference Between OPC and PPC Cement.

There are many aggregates whose specific gravity is more than 3.5 for making a heavy weight concrete. ; Gravel, Pea weighs 1 788 kg/m³ (111.62119 lb/ft³) with specific gravity of 1.788 relative to pure water. A cement is a binding substance utilised in construction work that hardens and gains strength quickly underwater. When sand is in wet condition, water is present in sand particles that change material quantity in the volume. Classification of Aggregates The variability in density can be used to produce concrete of widely different unit weights, see Table (1). In fact, the table shows that the lower the relative density of the aggregate used in the mixture, the lower the specimens mix density. Properties, advantages, Disadvantages. Since we measure mass in kg or lb and volume in litre or cubic meter or cubic feet, hence density is stated in Kg/m3 or lb/ft3. Aggregates produce the majority of the total concrete’s volume; hence, they affect concrete strength significantly. 4 4 4 f > g> Apparatus - The apparatus shall consist of the following: Balance -A balance or scale of capacity not less than 3 kg, readable and accurate to O-5 g and of such a type and shape as It should be hard, strong, dense, durable, and clean. Bulk density is equal to mass if the volume is unit. It is represented as, Apparent specific gravity = (Weight of oven-dried Aggregate at 100°c for 24 hours) / (Weight of water’s volume equal to that of aggregate’s solids excluding permeable pores), In concrete technology, specific gravity based on a saturated surface dry condition is generally used. The procedures for determining the maximum dry density, optimum moisture content, in-place density, in-place strength, and moisture content of soils, granular soil, and coarse aggregates in the field will be as follows: TEST METHODS Attachment I lists the test methods that will be used to test soils, granular soil, and aggregates. The specific gravity of aggregate excluding all pores is referred to as the absolute specific gravity. Soil C in each of the 3 aggregate size classes was separated into different density fractions by dry sieving described above. Crushed gravel shall be manufactured from gravel particles 90 percent of which by weight are retained on the maximum ... Earthwork/grading engineering - Aggregate Base Density Data. First Class Bricks must be homogeneous in texture without showing appreciable sign of efflorescence. 5.2 Relative density is used to calculate the volume occupied by the aggregate in various mixtures containing aggregate including hydraulic cement concrete, bituminous concrete, and other mixtures that are proportioned or analyzed on an absolute volume basis. Density #/Ft. As I said, earlier density is the material’s mass per unit volume. The substance that particles are retained on IS sieve no 480 (4.75mm) refers to coarse aggregate. The Nature of the work decides which size of coarse aggregate should be used. You will need: 935.00 mini bags of this aggregate type. Relative density (specific gravity) is also used in the computation of voids in aggregate in Test Method C29/C29M and in Test Method C1252. There are several materials used in building construction work. Air-dried aggregates (5 g) were placed into a centrifugation tube and 15 mL of sodium polytungstate solution with a density of 1.85 g cm −3 was added. The density of  OPC cement is = 1440 Kg/m3. Still, when used in the concrete mix, it should be adequately cleaned and tested to determine that the total percentage of silt, salts, clay and other such organic stuff does not pass the defined limit. However, it is well recognize that physical, chemical and thermal properties of aggregate substantially influence the properties and performance of concrete. It is the weight of aggregate needed to fill a unit volume of the container. In the above table, we have tried to cover the density/unit weight of generally used building materials. Aggregates are generally cheaper than cement and provide greater volume stability and durability to concrete.
