#0183;#32;No universally accepted mix design procedure for Cold Mix Recycling is available at present .Several procedures are available to determine the optimum emulsion and water content for CIR mixtures .In this research, the method of Ministry of Road and Transportation of Iran Specifications for Cold Mix Recycling that is similar to modified Marshall methods was used.
Thus, many additives have been developed to increase the tensile strength of concrete. One way is to combine polymeric materials such as polyvinyl alcohol, polyacrylamide, or hydroxypropyl methyl cellulose with the cement, producing what is sometimes known as macrodefectfree cement. Another method entails adding fibers made of stainless steel

produced by emulsion polymerization continues to expand incrementally. The wide range of the products which include synthetic rubbers, toughened plastics, paints, adhesives, paper coatings, floor polishes, sealants, cement and concrete additives, and nonwoven tissues can be produced by emulsion polymerization. More sophisticated applications are
Masonry cement additives are provided which, when interground with Portland cement, produce a masonary cement having superior workability, plasticity and board life, while unexpectedly also having advantageously low levels of entrained air. The additives of the invention enable the masonry cement producer to obtain these desired properties without replacing the limestone component of the
The additives of the invention enable the masonry cement producer to obtain these desired properties without replacing the limestone component of the masonry cement with more costly lime. The additives of the invention may be provided in aqueous solution, and thus, unlike emulsion additives, are stable for long periods of storage, even when subjected to extreme temperture excursions and cycling.
American Concrete Institute Method of Mix Design () This method of proportioning was first published in 1944 by ACI committee 613. In 1954 the method was revised to include, among other modifications, the use of entrained air. In 1970, the method of mix design became the responsibility of ACI committee 211.

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces is the most widely used material in existence and is only behind water as
