Study On Dry-mixed Mortar

Building mortar is indispensable in the civil construction project of building materials, the use of large dosage scope after concrete. The traditional mortar is on site by cement, lime paste and sand mixed with water and stirring. Its shortcoming is: the need for a large area of the raw material yard, mixture ratio control are not allowed, therefore, mortar quality can not be effectively guaranteed, material waste, environmental issues are prominent, seriously affecting the quality of construction projects and the construction function. A new type of green building materials mixed mortar as a building material field, depending on the quality of stability, good benefits, environmental protection and construction waste and greatly improve the construction environment advantages gradually on the construction stage. Development and application of dry mixed mortar is a new technique revolution, construction and building materials industry, is a main trend in the future of new material and new technology development. However, dry mixed mortar as a new thing, dry mortar industry has just started in China, people of this material social awareness is still low. Therefore, popularization and application of the technology of dry mixed mortar is still to be improved. This paper introduces the current research situation of dry mixed mortar at home and abroad, the popularization and application of the problems faced by the investigation and Study on the dry mixed mortar and the traditional on-site mixing mortar in the project quality, quality three aspects of economic cost and social benefit comparison. Through theoretical analysis and experimental study of a variety of raw materials in dry mixed mortar in mechanism, puts forward the quality of various basic composition material requirements, designed with ordinary dry mixed mortar ratio, test the dry mixed mortar consistency, water retention, compressive strength, bond strength and impermeability grades of various performance indicators, discusses the influence of various components of dry mixed mortar in the mortar performance, establishes the technical foundation and reliable for ordinary dry mixed mortar application.
