All slag early strength of grouting material and performance characteristics - key points of construction technology Zhengzhou grouting material manufacturers

Early curtain grouting materials and grouting material manufacturer early strength a grouting material price, the best rate and water cement ratio & # 8195;   Because of the slag and slag block bibulous rate is respectively 8% and 2% larger than ordinary sand, stone, sand and slag of shell type, and the surface is rough, so to achieve the same the early strength of grouting material fluidity, need to increase its appropriate water-cement ratio 7% 10%. In the preparation of early strength grouting material, should control the amount of slag sand, C20 early strength grouting material, for example, the best mining rate should be 36% 38%. Second, the tailings powder and water reducing the optimum content of the seam an agent & # 8195;   Viscosity, because of the large aggregate slag thickness inside the rent is poor, often mixed with the right amount of tailings powder ( < 0. 15mm） Calcium and water reducing the seam an agent, in order to improve the early strength of grouting material workability. By different dosage of tailings powder of slag cement mortar strength test and no wood calcium dosage early strength of grouting material strength test, the building materials summarizes the tailings powder of slag slurry optimal dosage is 130 - 150kg/m3； Wood calcium water reducing the best dosage of 3% - seam an agent 4%. Three, performance characteristics The compressive strength & # 8195;   All slag early strength grouting materials and ordinary early strength of gravel grouting materials at room temperature curing and compressive strength of steam curing contrast test results show that the mixture ratio under the condition of basically the same, mixed with calcium with tail mineral powder or wood and at the same time with the slag of calcium and tail mineral powder strong early compressive strength of grouting material with normal early compressive strength of grouting materials are basically the same or increase ( Up to 21. 9%) We has made a similar compressive strength of 30 groups of contrast test, the average combined strength is higher than ordinary sand the early strength of grouting material is about 5%.             Slag and slag all early grouting material and listen to the sand and grouting material elastic modulus of the grouting material standard comparison early strength type grouting material compressive strength ( Grouting material production equipment pictures MPa) Modulus of elasticity ( MPa） Note slag early strength grouting material in the 21st. 32. 66 x 10 Inner Mongolia chifeng grouting material manufacturer all slag early curtain grouting material and slag and fine aggregate is the difference between grouting material with slag sand, sand or ordinary ordinary early strength grouting material 22. 12. 55 27 x 10 common early strength grouting material. 22. 26 85 x 10 slag early strength grouting material. 32. 70 x 10 common early strength grouting material in the 21st. 42. 22 64 x 10 mineral sheers early strength grouting material. 52. 27×10              Thus, full slag early strength grouting material or slag early strength of grouting material elastic modulus are than ordinary low early strength of grouting material, so how to improve the slag or full slag early strength of grouting material elastic modulus, please further focus on the latest development of building materials technology test.
