1. Generally acceptable nominal size of aggregates for reinforced concrete, is
2. For heavily reinforced concrete member, the nominal maximum size of the aggregates should be restricted tomain bars
3. The average 28 days compressive strength of at least three 15 cm concrete cubes prepared with available water as compared to the average strength of three similer concrete cubes prepared with distilled water, should be at least
4. The pH value of water to be used in concrete shall generally be
5. All reinforcement should be free from
6. For all practical purposes, the modulus of elasticity of steel is assumed
7. M 30 grade concrete means, its compressive strength of 15-cm cube, is 30 N/mm2 after
