Compaction Factor Test for Concrete: Procedure, Apparatus & Formula (BS 1881-103)

Fresh concrete needs to flow into formwork, pack around reinforcement, and consolidate without leaving voids to avoid weakness. Engineers and concrete workers describe this behavior as workability, and the compaction factor test is one of

ASTM C136 Dry Sieve Analysis of Fine and Coarse Aggregates

TeamCivil Concrete, Tests

This post describes the procedure of ASTM C136/C136M to determine the particle size distribution of fine and coarse aggregates by sieving. The test shows how much material is retained on and passes each selected sieve.

ASTM C131 Los Angeles LA Abrasion Test of Coarse Aggregate

TeamCivil Concrete, Tests

This post describes the procedure of ASTM C131/C131M to determine the resistance of coarse aggregate smaller than 37.5 mm in size to degradation using the Los Angeles testing machine. The action includes abrasion, impact, and

ASTM C128 Obtain Specific Gravity and Absorption of Fine Aggregate

TeamCivil Concrete, Tests

Specific Gravity and Absorption of Fine Aggregate In this article, we discuss the methodology and test procedure described in ASTM C128 to conduct the experiment related to the specific gravity and absorption of fine aggregate.

Rebound Test: Equipment – Operation

TeamCivil Concrete, Tests

In this article, the Rebound Test (schmidt hammer test) is outlined. The Swiss engineer Ernst Schmidt, first developed a practicable rebound test hammer in the late 1940s, amd modern versions are based on this. Figure 1 shows the
