Abstract

The invention discloses a reinforcing pumping admixture for concrete. A preparation method of the reinforcing pumping admixture comprises the following steps of firstly preparing a rheological agent,wherein the rheological agent is prepared from the following raw materials in parts by weight: 20 to 30 parts of magnesium aluminum silicate, 5 to 10 parts of bentonite, 3 to 5 parts of dihydroxyl polydimethylsiloxane, 2 to 5 parts of maleic anhydride, 1 to 2 parts of tetramethyldivinyldisilazane and 20 to 30 parts of durene. The uniformity of slurry of the concrete which is provided by the invention and into which the reinforcing pumping admixture is added is enabled to subsequently become good; the viscosity is decreased; the flow speed of pulp becomes quick; the suspension property of an aggregate in the concrete is enhanced; the bottom deposition phenomenon cannot occur within a longer time; the pulp is enabled to more uniformly enwrap the aggregate and the rheological agent in the reinforcing pumping admixture is used for ameliorating the flowability of the pulp.

Description

technical field [0001] The invention relates to an enhanced pumping agent for concrete, which belongs to the field of concrete. Background technique [0002] Concrete pumping agent is also a kind of concrete admixture. It is defined as: an admixture that improves the pumpability of concrete mixes. With the development of commercial concrete, the status of concrete pumping agent has become increasingly prominent. At present, there is no significant improvement in improving the homogeneity of concrete, and it is difficult to accurately control long-distance concrete pumping, so that the success rate of concrete continuous pumping construction is very low, and the pumping distance is relatively short. The mechanical properties of concrete are difficult to guarantee. Contents of the invention [0003] In order to solve the problems existing in the pumping agent materials in the prior art, the present invention provides a reinforced pumping agent for concrete and a manufactu...
