UGM the four characteristics of high-strength non-shrink grout material application is introduced

UGM high-strength non-shrink grout UGM high-strength non-shrink grout material as a new kind of grouting material, UGM ( No shrinkage of high strength grouting material) In the power plant equipment base, bolt hole and so on has been widely used in the secondary grouting. It is made of high strength cementitious materials ( High strength grade cement) , grouting the seam an agent and some trace of modified materials according to certain proportion after grinding, together with 3 ~ 5 mm in diameter aggregate to form, its reaction with water to form expansion crystal so as to realize their own without shrinkage. It has the following characteristics. 1, durability. UGM for inorganic material, not aging, for reinforcement corrosion. Secondary perfusion, for small space with UGM directly as grouting material of water, water content of 13% ~ 15% for UGM quality; For the second infusion of large space, can add 5 ~ 10 mm size stones, quality mixture ratio for the UGM: stones: water = 1-0. 5: ( 0. 14 ~ 0. 18) Water, no segregation of the grouting material shall prevail. 2, super early strength. Can be in 1 ~ 3 d obtain relatively high compressive strength, under the condition of guarantee sufficient maintenance, 2 ~ 3 d can be installed equipment. 3, not shrink. Reliable early expansion and long-term contractive can guarantee the anchor bolts and foundation and the old and new grouting material solid combination. 4, good liquidity. In the case of low water cement ratio can obtain great fluidity, can fully fill the gap.
