2. A latex admixture is an emulsion in which a polymer is dispersed in water. Thus, a latex-modified concrete (LMC) is a portland cement concrete which includes an emulsion of water and polymer. 3. "A polymer latex consists of small (0.05- to 1.0-ym-diameter) spherical particles held in suspension by the use of surface-active agents.

Sulphate Resistant Cement (SRC) By maintaining C3A level within the specified limit of 3.5%, our Sulphate Resistant Cement is more resistant to Sulphate attacks and is suitable for use in foundations near seashore and canal linings.

in the cement. ii. Lower temperatures will delay the setting time. iii. SRC cement gives higher retardation level than ordinary cement. iv. Using more than one type of admixture in the same concrete mix could affect the setting time. v. Retardation level is increased when cement replacement materials are used in the concrete mix.
