A: on the basic requirements of epoxy grout!

Explanation of epoxy grout in construction projects is the basic technical requirements of: ( 1) Requirement for high volume based epoxy grout integrity, continuous casting, general requirements epoxy grout entity. Construction technology should be layered casting, layered tamping. To meet the structure security and the strength of the requirements of different construction stages. （ 2) To meet the epoxy grout mixing, pouring, the workability of the requirements of molding process. （ 3) To meet the durability of the requirements of design and use of the environment. JGJ55 - ordinary epoxy grout mix design procedures 2002, gm silicate used in cement and fly ash in epoxy grout GB/T1596 - 2005, epoxy grout GB50204 - structural engineering construction quality acceptance specification 2010, epoxy grout structure design. What are the basic requirements for preparation of epoxy grout. Epoxy grout production of basic requirements: 1, choose the quality qualified raw materials; 2, optimization of mixture ratio; 3, qualified production equipment; 4, skilled related operators; 5, reasonable casting, molding, curing process. The basic requirement of epoxy grout on the sand. 1, sand particles of the total surface area is smaller, the sand as thick as possible. In the epoxy grout slurry is to achieve effective bonding surface through the aggregate particles, the aggregate total surface area is smaller, the cement, the section. The basic requirement of the epoxy grout mixture. The basic requirement of epoxy grout mixture: workability, slump, water retention, Epoxy grout has the following points to determine the performance of 1 mixture and aggregate to clean silt content not more than 3% of 2, 3, sand coarse aggregate gradation to reasonable to adopt the configuration of coarse sand epoxy grout should consider what are the basic requirements. Raw materials, Cement, fly ash and mineral powder, sand, stone, admixture, etc. ) The physical and chemical properties of epoxy grout strength ( Safety guaranteed) , workability and slump ( Work performance is better) , durability index ( Or safety) 。 Used in the construction of epoxy grout, generally must meet the basic requirements, used in the construction of concrete, generally must meet 1, intensity, 2, workability, 3, durability, 4, economy basic requirements. Second, how to detect whether the epoxy grout avenue requirements: method 1: slump law: a measure of the liquidity. What are the basic requirements epoxy grout casting? Strength, workability mainly control the water cement ratio, sand ratio, slump, mixing, pouring and pouring time!
