# aggregate density table

Aggregates produce the majority of the total concrete’s volume; hence, they affect concrete strength significantly. A relative density of at least 70% is recommended. The approximate value of bulk density for aggregate usually used for normal-weight concrete varies between 1200-1750 Kg/m 3 or 75 to 110 lb/ft 3. However, it is well recognize that physical, chemical and thermal properties of aggregate substantially influence the properties and performance of concrete. The density of sand varies according to its conditions ( Dry or Wet or packed). Table 6F-1.01: Effects of Intrinsic and Manufactured Properties of Aggregates as Controlling Factors on Engineering Properties of Granular Material in Pavement Layers Manufacturing date, grade and type play vital role in purchasing right cement and there should be no lumps in it. 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. gradation for compaction control of aggregate materials in the field to avoid inadequate compaction. Construction aggregates are extracted from natural sand and gravel deposits or quarried from rock formations. It helps to convert quantities by weight to by volume. Hereabouts, for coarse aggregates, the standard test process has been described in ASTM C 127(AASHTO), and for fine aggregates, the standard test practice has been described in ASTM C 128 (AASHTO). Only cement is unusually used; it is used to bind coarse and fine aggregate to produce mortar and concrete. [2] Relative Density of Aggregate [1] The relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal volume of … It also indicates the aggregate grading and shape. Density of Cement Ordinary Portland cement=1440kg/cum Rapid Hardening cement =1350kg/ cum Bulk density of coarse aggregate=1600 to 1800 kg/ cum; Construction Aggregate Calculator. Bulk Density = Weight of aggregate / Container of unit volume, Aggregate Contains both permeable and impermeable pores. 2) Do not use additives such as but not limited to lime, cement, or fly ash to modify aggregates to meet the requirements of Table 1, unless shown on the plans. ; Gravel, Pea weighs 1 788 kg/m³ (111.62119 lb/ft³) with specific gravity of 1.788 relative to pure water. Density of Portland Cement Number of 25kg bags per m3 Answer; 1600 kg/m3 (1600 (kg/m3) x 1 (m3))/25 (kg bags) 64 Bags You will need: 24.93 bulk bags of this aggregate type. Some of natural commercially used aggregates are as follows: 1. When sand is packed, sand particles are forced to form narrow disposition, resulting in more material in the volume. In addition, it calculates the total weight if you know the density of the crushed material. It is presented in Kg/m3 or lb/ft3 and shows the construction material’s compactness. 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. I hope it helps you. When sand is in wet condition, water is present in sand particles that change material quantity in the volume. Based on their size, the aggregates are named as: The material below 4.75 mm size refers to fine aggregate. 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. TABLE OF DENSITIES OF THE MORE COMMON MATERIALS. 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. Hard wood Characteristics and application, Ratio of Cement and Sand for ‘Plastering’. Aggregate Density Table, free PDF download. Divide Cubic Feet by 27 = Cubic Yards. Density, also known as the unit weight, is the mass per unit volume of the material.
