specific gravity and water absorption test of aggregate

Specific Gravity and Water absorption test on Aggregate

26 July 2021 Sreepriya R Aggregate, Building Materials

Specific gravity and water absorption test are significant tests on aggregates. Perhaps aggregates are the fundamental and essential components of concrete and play a significant role in the design mix of concrete. More than 70 to 80 per cent of the volume of concrete is aggregate. Hence the water absorption and specific gravity test are essential tests.
The specific gravity is the measure of strength, while water absorption indicates the porosity of aggregates.

Lightweight Aggregate: Manufacturing, Properties and Types

13 June 2021 Jefy Aggregate, Building Materials

Lightweight aggregate is a widely used construction material owing to its versatile properties. Lightweight aggregate is a coarse aggregate used to make lightweight concrete for structural as well as non-structural applications. In this blog, I will walk you through what is a lightweight aggregate, its properties, applications and manufacturing process. The lightweight aggregate used in concrete may have any form, including cubical, rounded, angular, and other shapes. Its workability is directly influenced by its form and texture. These aggregates are known for absorbing little water and maintaining their low density.

Soundness test on Aggregate | Sample selection and procedure

6 April 2021 Sreepriya R Aggregate, Building Materials

Soundness test determines the disintegration of aggregates due to weathering. This includes freezing, thawing, marine condition etc. However, the weak and porous aggregate shows a change in weight during this soundness test.

Shape test on Coarse Aggregates – Flakiness Index and elongation index

6 April 2021 Sreepriya R Aggregate, Building Materials

Shape test on coarse aggregates constitutes flakiness Index and elongation index tests. The particle size and shape of aggregate is one of the major factors

Impact test – Determination of aggregate Impact value

30 March 2021 Sreepriya R Aggregate, Building Materials

Impact test on aggregate is determines the ability of an aggregate to withstand sudden loads. Aggregates are the significant factor that contributes adequate strength to concrete. Therefore it is important to obtain the right quality aggregate for construction. Aggregates are often subjected to impact due to the movement of vehicles on road. Hence it should possess good impact resistance or else it results in disintegration and breaking into pieces.

Los Angeles Abrasion testing of Aggregates.

Los Angeles Abrasion test of Aggregates

29 March 2021 Sreepriya R Aggregate, Building Materials

Los Angeles Abrasion test is to measure the abrasion resistance value of aggregates. Aggregate is the fundamental and essential component of concrete, flexible pavements, etc. More than 70 to 80 percent of the volume of concrete is aggregate. Aggregates are the main ingredients of concrete, flexible pavements, etc., so quality matters when it comes to aggregates.

Aggregate crushing test – Strength of aggregate

28 March 2021 Sreepriya R Aggregate, Building Materials

Aggregate crushing test is done to find out the strength of aggregate which is the fundamental and essential components of concrete, flexible pavements, etc. More than 70 to 80 per cent of the volume of concrete is aggregate. Aggregates are a very important component of concrete, so the quality really matters when it comes to aggregates. Furthermore, their uses include flexible pavements, railway ballast, etc.
