since the strength may vary when the stone is wet, the strength tests (i.e. compressive strength, flexural strength, modulus of rupture) are sometimes performed using wet stone specimens. For the dry condition, the stone specimens are dried in an oven at 60°C ±2°C (140°F ±2°F) for at least 48 hours or

The use of limestone in the construction industry has been increasing due to bene ts as aggregate. Some of these bene ts include good strength, low possibility of alkali-silica reaction and the decrease in drying shrinkage in concrete. This research discusses the consumption and general characteristics of the lime-stone aggregate in USA and Japan.

This research work investigates and evaluates the effects of varying lime composition on the compressive and flexural strength of compressed silicate limestone bricks and compares the results to the local blocks and bricks used in the Kenya market. The mix ratio used to make limestone bricks was binder (cement replaced with hydrated lime powder), sand and water cement in ratio of 1:5:0.4.
Compressive Strength. A key difference between UKCSA Full Members and other cast stone manufacturers is the high compressive strength of their products, which makes them significantly more robust and durable.. The minimum standard required of UKCSA Full Members represents over 40% increase in compressive strength above that indicated in the British Standard for Cast Stone, BS
