![]() ![]() It is found that high content of suspended particles does not affect the strength of the concrete, but affect other properties of the same. ![]() If the mixing water contains suspended particles in an amount up to 0.02 percent by weight of total water used in concrete, it will not affect the concrete properties. The effect of various properties on the concrete properties are explained below:Įffect of Suspended Particles in Water on Concrete Properties Water Impurities and their Effect on Concrete Properties Table-1: Effect of Different Salts in Water on Compressive Strength of Concrete Salt Content in Water (%) The table-1 shows the reduction of compressive strength of concrete structures by the different salt content present in water. ![]() This problem in concrete structures due to water quality problems is more severe in the tropical regions, mostly in that mix that is lean. The high content of chlorides in water tends to show surface efflorescence, dampness persistently and makes the reinforcement steel prone to corrosion. This decrease is the strength of concrete compared with that obtained by the concrete using distilled water. Various tests have shown that the usage of water or structure that are constructed near to a water body with the excessive amount of salts (dissolved salts) tend to decrease the compressive strength of the concrete by an amount of 10 to 30 percent. Up to 10% of the controlled test is adequate to measure the quality of the mixing water.Īs per IS:456-2000, a difference in the initial setting time by a value +/-30 minutes, given that the initial setting time is not less than 30 minutes is prescribed.Ĭoncrete is affected by the effluents that are expelled out from the sewerage works, sugar and the fertilizer industry, paint, gas works, and textile industries.
