Lightweight Aggregate : Manufacturing, Properties and Types
Lightweight aggregate is a coarse aggregate used to make lightweight concrete for structural as well as non-structural applications.
Category: aggregate
Soundness test on Aggregate | Sample selection and procedure
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.
Specific Gravity and Water absorption test on Aggregate
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 and significant tests .
Los Angeles abrasion Test on Aggregates
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.
Shape tests on Coarse Aggregates- Flakiness index test and Elongation Index Tests.
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 affecting the quality of the concrete.
Aggregate crushing test to find Strength of aggregate
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.
