Stripping Value Test On Road Aggregates
What is Stripping Value Test? The stripping value of aggregates is determined as the ratio of the uncovered area observed visually to the total area of aggregates, expressed as a percentage. Bitumen and tar adhere well to all normal types ...
Elongation Index Test on Coarse Aggreagtes
Elongation index of an aggregate is the percentage by weight of particles whose greatest dimension (length) is greater than one and four-fifth times (1.8 times or 9/5 times) their mean dimension. It is measured on particles passing through mesh size ...
Properties of Aggregates and its Values for use in Construction
Properties of Aggregates and its Values for use in Construction Properties of aggregates such as bulk density, specific gravity, voids, water absorption and its values are presented in this article. 1. Aggregates: Bulk Density, Specific Gravity and Voids Bulk Density ...
Grading of Aggregates and Grading Limits
Grading of aggregates are determination of particle size distribution of aggregates. Grading of aggregates is an important factor for concrete mix design. These affect the concrete strength as well as durability. Proper grading is important for concrete construction. Following tables ...
Grain Size Analysis of Aggregates – Particle Size Distribution Test
Test for grain size analysis or sieve analysis of aggregates are done to determine its particle size distribution, fineness modulus, effective size and uniformity coefficient. Grain Size Analysis of Aggregates Fine aggregate is the sand used in mortars. Coarse aggregate ...
Bulking of Sand – Cause, Tests and Importance
Bulking of fine aggregate or sand is the phenomenon of increase in sand volume due to the increase of moisture content. Bulking test on fine aggregates has to be performed before using it in construction. This article describes the procedure ...
Determination of Specific Gravity of Fine Aggregates
Specific gravity of fine aggregate (sand) is the ratio of the weight of given volume of aggregates to the weight of equal volume of water. The specific gravity of sands is considered to be around 2.65. Apparatus for Specific Gravity ...
