COMPRESSIVE STRENGTH OF CONCRETE USING LATERITIC .
workability and compressive strength of normal concrete with water/cement ratios are valid for laterized concrete. Salau [4] observed in his paper "Longterm deformations of laterized concrete short columns" that there were not many variations between the creep deformations of laterized concrete and normal concrete short columns.
PROPERTIES OF DIFFERENT ARTIFICIAL LIGHTWEIGHT .
Aggregate crushing value (ACV) The strength of aggregates is an important element in determining concrete strength. Thus, determining the strength of the three types of plastic aggregates and NA is crucial because of their indefinite strength. Aggregate crushing value (ACV) is used to identify aggregate crushing strength. The ACV test was

Effect of Aggregate Properties on the Crushing Strength of ...
This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest workability followed by shingles stone brick khoa of aggregates.
