Sika South Africa is delighted to announce the opening of their new concrete laboratory in Johannesburg. Business unit concrete will use this facility to further increase their core business as there is an increase in demand in the Gauteng area for Sika concrete admixtures. Sika is improving its service in this region by offering high quality technical support, backed by relevant concrete testing facilities and procedures to quantify and optimise their concrete quality and cost efficiency. The laboratory will enable the Sika concrete technologists within the Gauteng area to optimise concrete mixes for semi dry pavers, wet cast precasters, RMC producers (Ready mix concrete), and testing of Shotcrete materials used in tunnelling and mining.

In the main concrete laboratory mixes are designed and tested to determine where they can be adjusted for optimization. The Sika concrete admixtures can improve water reduction, allowing for further reduction of cementitious binder contents while still maintaining concrete workability with similar or improved strength development.
