Crushing Test. Compressive Strength Test (IS: 1121 (Part I)) Samples of stone weighing at least 25 kg each of the unweathered spcimen should be obtained from quarry. To test stone for compressive strength, specimen pieces in the form of cubes or cylinders are made from samples of rock. The lateral dimension or diameter of test piece should notSandstone is better resistant to fires. Despite having poor strength, argillaceous stones like Slate and Laterite are highly fire resistant. 9. Durability. Building stone must possess high durability.

Specifics of Studying Crushability of Construction Rocks
Findings: The article presents the results of studying crushability of construction rocks by different methods. It was found that porosity, particle size, grain shape and loading effort application rate are the factors affecting the strength of crushed stone grains. Mechanical stresses undergone by the rocks during blasting and disintegration2. Materials and methods. LWA having a unit weight of 1536 kg/m 3 and limestone crushed aggregate having a maximum size of 19 mm, procured from a local aggregate crushing facility were used as LWA and NWA, respectively. Locally produced crushed stone sand having fineness modulus of 4.18 was used as fine aggregate.Lightweight aggregate concrete produced with crushed stone

Stones Properties Basic Civil Engineering Questions and Answers
Basic Civil Engineering Questions and Answers Properties of Stones. This set of Basic Civil Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Properties of Stones”. 1. For a good building stone how much is the required crushing strength? a) Less than 50 N/mm 2. b) Greater than 100 N/mm 2. c) 155 N/mm 2.3. A good building stone should be fine-grained because they are having good crushing strength as well as good texture. 4. The good building stones should be compact because these can resist more pressure. 5. A good building stone should be heavily weighted because the weight of stone indicates the porosity and density of the 16-Requirements of Good Building Stones Civil Lead
