Importance of Different Testing on Road Aggregates

Posted on 11th July 202013th March 2022 By Malay Sautya
Importance of Different Testing on Road Aggregates

Importance of Different Testing on Road Aggregates Importance of different testing on road aggregates are as follows: 1. Abrasion test This test is performed to find out the hardness i.e resistance to abrasion of the stone aggregate. It is very important to know the aggregate hardness value before it used in road construction. 2. Impact…

Different Size of Aggregates Used For Different Purposes

Posted on 14th June 201923rd February 2022 By Malay Sautya
Different Size of Aggregates Used For Different Purposes

Different Size of Aggregates Used For Different Purposes For the same workability and strength, concrete having large size aggregate requires less amount of cement than in concrete having smaller size aggregate. Hence, in large bulk works large-sized aggregates are preferred.   Leaser cement reduces the heat of hydration and thereby the shrinkage cracks. Use of…

What is Grading And Proportioning of Aggregates

Posted on 13th June 201923rd February 2022 By Malay Sautya

Grading of Aggregates The art of doing gradation (particle size distribution) of an aggregate as determined by sieve analysis is called grading of aggregate.   The grading of aggregate has a considerable effect on workability, uniformity & finishing qualities of plastic concrete which ultimately affec& other properties of hardened concrete. Proportioning of Aggregates The art…

Bulk Density of Aggregate

Posted on 13th June 201923rd February 2022 By Malay Sautya

Bulk Density of Aggregate The bulk density of an aggregate may be defined as the mass of the material in a given volume. It depends on how densely the aggregate is packed.   The other factors affecting the bulk density are the particle size & shape, the grading of the aggregate and moisture content. Bulk density…

Functions Of Fine and Coarse Aggregate in Concrete

Posted on 29th May 201923rd February 2022 By Malay Sautya
Functions Of Fine and Coarse Aggregate in Concrete

Functions Of Fine Aggregate in Concrete Fine aggregates perform the following functions:   1. It assists in producing workability and uniformly in mixture. 2. It assists the cement paste to hard the coarse aggregate particles. 3. It helps to prevent possible segregation of paste and coarse aggregate particularly during the transport operation of concrete for…
