Fly ash as a carrier of the composite powder plasticized mortar Study


Pulp improved workability, improved performance of mortar seepage water, lower water-cement ratio, and reduce engineering costs,[link widoczny dla zalogowanych], reduce environmental pollution. l Pina plastics powder with wet fly ash difficult for the South plant, gypsum plaster model used commercially for industrial use, surfactant, soap for the self-developed derivatives (FH), ratio: Fly 95 ( a dry powder dollars), gypsum 4, FH1. FH 2O first dilution with water, dried and fly ash mixed evenly, then add gypsum powder, a mixture of grinding to a particle size less than 200 mesh can be. 2 test and the results of the preparation of plastics in different mortar mix,[link widoczny dla zalogowanych], the consistency of mortar, hierarchical level, and test the performance of bleeding and mortar made with plastic 7.07 × 7.07 × 7.07cfi ~ the test block, Determination of the compressive strength, mortar and cement mortar and mixed test results were compared. The results are shown in Table 1. 1 mortar decay ratio of the tank and sample t test with a note bearing bearing silicate mixture to 325 * mud mortar test results show that the rejection of artificial mixing, mortar powder added to plastics, the next, the mortar was reduced sink , significantly lower hierarchical level, the amount of bleeding decreased by 50 or more of lime, the situation does not reduce the water consumption rate has dropped; mortar compressive strength of 7 and 28 days a slight utilization of fly ash to improve in 1996 4; in maintaining and commutativity conditions, water can be reduced about 15.3 3.1 plasticization mechanism of powder plastics powder into mortar later. Highly decentralized role of active substances with water, quickly press evenly distributed in the cement particles, emulsified by mixing a large amount bubbles, these bubbles are adsorbed on the cement or sand, and can slow down the settling velocity of mortar. Because the cement particles adsorbed surfactant hydrophobic, the surface layer of adsorbed film can be formed, so that there is a certain cement particles hydrophobic. In aqueous medium bonded to each other. Thus, not easy to loose mixture segregation. In addition, a large number of tiny air bubbles with a large surface area, but also can effectively reduce the moisture from the mortar in the segregation speed. The buoyancy of the bubble,[link widoczny dla zalogowanych], but also undermine the sand and cement to ask the pores, it can improve water retention of mortar. 3.2 As the hydration of cement and carrier, slurry of Ca (OH). Concentration increased. Hydration of the active substances with the formation of stable calcium soap film and increase the stability of the bubble, stable foam which can play a role of lubrication, the mortar by the external force. Deformation capacity is increased, thereby improving the plasticity and workability of mortar. 3.3 The main components of fly ash amorphous SiO, and A1. O, in a certain fineness and alkaline conditions can stimulate the potential activity and cement hydration mutual promotion and incorporation of gypsum on the early strength of mortar play a role in promoting, therefore, mortar powder mixed with plastics later. Its strength does not decrease. 4 mortar to use plastics powder by weight of cement 1 ~ z uniformly mixed with cement. Then asked to join mortar sand, water, etc. Mix well. With less water because of its role and place of the performance of lime,[link widoczny dla zalogowanych], water should be appropriate to reduce the dosage of lime can also be reduced more than 5O. Plastics with a ton of powder, lime can reduce the amount of 20 to 30 tons. Plastics powder by 500 yuan / ton. Lime i00 yuan / ton, using the powder can save a ton of plastics raw material costs 1,500 ~ 2,500 yuan, if the combined transport, working hours and other costs, and training can reduce the synthesis of the 2,000 to 3,000 yuan. Significantly reduced the amount of lime, followed by environmental pollution caused much less step. ● BIBLIOGRAP i dig Translations of concrete plus Jing (second episode).
