A significant volume of waste latex paint exists in New Zealand, with the rate of supply rapidly growing, prompting an investigation into the use of waste paint as a polymeric admixture in concrete due to similarities in chemical compositions of waste paint and polymeric admixtures.

Chemical admixtures are not a substitute for suitable concrete mixture proportions and acceptable construction practices. This report deals with commonly used admixtures other than those assigned to other ACI committees. Materials, such as mineral admixtures, used to produce concrete are not discussed in this report.
International Standards IS: and IS: cover only some aspects of the use of admixutres in concrete. Tables in the paper give specifications for: (1) various mixtures according to Standard ASTM 49482; (2) various types of admixtures according to British Standard BS 5075: Part 1: 1982; (3) superplasticising admixtures according to British Standard BS 5075: Part 3: 1985.

Portland cement concrete is prone to drying shrinkage cracking. It is susceptible to attack by sulphates and has an undesirable reaction with certain aggregates (ASR). Generally, when one accelerates the gain in strength of portland cement concrete through finer grinding or chemical additives, there is a significant increase in drying shrinkage.
The first and most important role of chemical admixtures is to reduce the water : binder ratio. Specifications and Test Methods IS 9103, ASTM C494, ASTM C 1017, BS 5075 (withdrawn) and BS EN 934 part 1, 2, 6 with supporting test methods are commonly used, for classifying and testing chemical admixtures for concrete.
Mineral admixtures are extensively used in the production of concrete for attaining good strength and durability characteristics. Fly ash, rice husk ash, metakaolin and silica fume are the commonly used mineral admixtures. Apart from strength durability of the concrete is also a main concern now days. Concrete is a porous material.
