Many websites are giving different value for "total dry volume", but the values
Get Price(between 6 and 12%) for concretes with slumps of 125 to 200 mm (5 to 8 in.) without the retardation associated with high dosages of conventional (normal) water reducers. Normal water reducers are intended for concretes with slumps of 100 to 125 mm (4 to 5 in.). Mid-range water reducers can be used to reduce stickiness and improve
Get PriceShort term modular ratio = E s / E c Es = modulus of elasticity of steel (2 x 10 5 N/mm 2) Ec = modulus of elasticity of concrete (5000 x SQRT(f ck) N/mm 2) As the modulus of elasticity of concrete changes with time, age at loading etc the modular ratio also changes accordingly. Taking into account the effects of creep and shrinkage partially IS code gives the following expression for the long term modular ratio.
Get PriceThe investigation aims to study the effect of re-vibration time and amount of steel fiber on the properties of concrete made with crushed cement-sand mortar as coarse aggregate. Three mixes were prepared with 0.00, 50 and 100 percent replacement of natural gravel by crushed cement-sand mortar aggregates. Mix proportions of concrete were 1: 2: 3 by weight.
