Latex-modified Concretes and MortarsTransportation Research Board, National Research Council, 1992 - 58 pagina's This synthesis wil be of interest to materials engineers, construction engineers, maintenance engineers, pavement contractors and others interested in the use of latex-modified mortars (LMM) and concretes ( LMC). Information is provided on material properties of various LMM and LMC, as well as current construction practices used for LMM and LMC. Potential applications for LMM and LMC are also included. The use of innovative modified portland cement mortars and concretes for construction and maintenance applications is growing. This report of the Transportation Research Board describes the current state of the practice with respect to the use of latex-modified portland cement concretes and mortars. The extent of use of each material (including case histories), based on results of surveys of state highway agencies and a review of the literature, is summarized. |
