When used in concrete block manufacture, BLOCKSPEED allows quicker turnaround, increased strength at an earlier age and increases ultimate strengths without. Conplast SD400 is a chloride-free accelerating admixture specially formulated for optimum performance across a wide range of static and mobile (egg-laying) block paving and masonry production equipment. It is supplied as a straw coloured solution which instantly disperses in water.

Conplast SD400 formerly Conplast Blockspeed – To provide quicker turnaround by accelerating setting and early strength gain of semi-dry concrete units.

Admixtures Overview

Admixtures are materials other than cement, aggregate and water that are added to concrete either before or during its mixing to alter its properties, such as workability, curing temperature range, set time or colour.

Some admixtures have been in use for a very long time, such as calcium chloride to provide a cold-weather setting concrete. Others are more recent and represent an area of expanding possibilities for increased performance.

Not all admixtures are economical to employ on a particular project. Also, some characteristics of concrete, such as low absorption, can be achieved simply by consistently adhering to high quality concreting practices.
