The effect of over dosage of concrete retarder daratard 40 in concrete

More than 70 % of insitu concrete is produced now by the ready mixed concrete industry in Malaysia. With the increases in economic growth and demand for highrise buildings as well as infrastructures make the industry to determine its own standards of the production by trial mixed design. The issues...
