Culture Stone Quickly Paste Adhesive Research

Culture stone beautiful, high-end atmosphere, durable, is now gardens, villas popular wall decoration materials. But facing stone generally heavier, larger load surface, in the construction prone to slippage, workers need righting cultural stone in the construction, which greatly reduces the efficiency of construction stone culture, and now irreversible rise in labor costs cause of high culture stone paste charges. Slip is now mainly due to the initial bond strength adhesive enough, and national norms only late strength index, which is generally the adhesive can be achieved, but not in the early stages of cement hydration requirements. In this paper, the viscosity of the mortar as an indicator to increase the initial adhesion strength adhesive made a systematic study.Studies have shown that: Mortar on initial adhesive strength greater than mortar, Mortar with increasing ratio of the viscosity of the mortar in reducing the initial adhesion strength decrease, considering the 1: 1 Comparison of Mortar good; the smaller fineness modulus of sand, the greater the viscosity of mortar, adhesive mortar higher early tensile bond strength, better anti-slip properties; HPMC added to make the bleeding rate of mortar, reduce the degree of stratification can improve the cohesiveness and sag resistance mortar, while its nature as HPMC viscosity increase and the corresponding increase, when its content exceeds 0.6% by mass of cement, cohesiveness increased slowly, viscosity exceeds 200000 mPa.s, the slow increase in initial strength, and the viscosity is too poor workability; dispersible polymer powder in the initial bond strength increased significantly, and can increase the workability of the mortar, adhesion, toughness. Wacker 4015,4023,5010,5044 optimal dosage were 0.7%, 1.0%, 1.5%, 1.0%. Consider the size of the initial adhesive strength, resistance to cracking, physical and mechanical properties, Wacer content in 4023 to 1.0% for the best powder; anhydrous calcium chloride and triethanolamine improve the initial bond strength of mortar It has a positive effect, optimal amount of anhydrous calcium chloride 2.5%, relative to the base at this initial mortar adhesion strength increased by 61.06%. Optimal amount of triethanolamine 0.09% at this optimal dosage as compared to the initial bond strength of mortar base increased 60.4%. Consider triethanolamine overdose can cause serious retarding effect, choose anhydrous calcium chloride content is 2.5%; the final mix is: m(PO42.5R): m(ultrafine sand): m(4023N): m(HPMC): m(CaCl2) = 1: 1: 1.0%: 0.6%: 2.5%. After testing shows that the proportion of the country to meet the standards, the actual construction has a certain significance.
