Different models of the grouting material mineral admixtures and the choice of water reducing the seam an agent - Bearing grouting material price

grouting material type high-strength non-shrink grout material type high strength grouting material selection model a, mineral admixtures mineral admixture in the mechanism of the grouting guess first embodied in three aspects. One is the particle shape effect, can reduce grouting material model of mixing water consumption; Secondly, fine aggregate effect, fine particle filled with to cement particle hebei grouting material manufacturers selling can't fill the pore model, the interface defect of cement paste and aggregate decreases, close sexual advances, to advance grouting material model of strength and permeability resistance; A third is chemical activity effect, use its gelling, pozzolanic activity will be the interface between cement paste and aggregate a lot of calcium hydroxide crystal translate into strength and fine a better C - S - H gel that improve the interface defects, progress strength of grouting material model. Different kinds of mineral admixture, because of the different nature of its own, in grouting guess that each have emphasize particularly on the above three kinds of effect, but to advance grouting material model and performance, improve the interface defects, progress strength can have very good effect. But in the early inhibition of drying shrinkage cracking favourable circumstances, the strength and elastic modulus, antifreeze harmony carbonization resistance has a different degree of adverse effects. Two seam, water reducing agent selection of high performance water reducing the seam an agent sort is more, also has given priority to with water reducing together a variety of performance. So in manufacturing especially fine Bridges grouting material model, chooses the water reducing the seam an agent it is necessary to match after determined through laboratory test, the design chooses the type of quality cooperation than prestressed grouting material type activity subject to construction units total engineers and supervision engineer sign can be used only to recognize, and lest affect bridge irrigation hebei shijiazhuang grouting material model factory engineering quality and appearance quality of the thick liquid material.
