Acid Test: laboratory test of stone in civil engineering construction

Acid Test

laboratory test of stone

Acid Test is normally transferred out on sandstones to check the appearance of calcium carbonate, which debilitates the weather endure quality.

 In this test, a sample of stone considers about 50 to 100 gm is taken and kept in a suspension of one percent (%) hydrochloric acid for seven (7) days. The suspension is agitated at intervals.

Quality of good building stone

 A good building stone keeps up its sharp edges and holds on its surface intact. If edges are shattered and powder is established on the surface, it specifies the existence of calcium carbonate. Such stones will have needful weather resistance.
