Effects of Lignosulfonate and Temperature on Compressive Compressive Strength of Concrete Concrete Cubes What

Effects of Lignosulfonate and Temperature on Compressive Strength of Cement The compressive strength of concrete increased due to an addition of the lignosulfonate It reached a maximum value at the addition of lignosulfonate as much as 02 of the cement weight at various temperatur The addition of the additive at a higher level resulted in a decrease in the compressive strength Compressive Strength The compressive strength of any material is defined as the resistance to failure under the action of compressive forc Especially for concrete compressive strength is an important parameter to determine the performance of the material during service conditions
