Concrete synergist with strong workability and bleeding resistance and concrete

Abstract

The invention discloses a concrete synergist with strong workability and bleeding resistance. Raw materials of the synergist comprise the following ingredients (by weight): 8-15 parts of allyl polyoxyethylene ether, 5-10 parts of maleic anhydride, 10-16 parts of polyacrylamide, 3-8 parts of polyvinyl alcohol, 2-6 parts of methyl methacrylate, 4-8 parts of fiber, 2-5 parts of polystyrene microspheres, 1-5 parts of polypropylene glycol, 4-9 parts of polysodium methacrylate, 5-10 parts of isobutenol polyoxyethylene ether, 1-5 parts of rice bran, 0.1-2 parts of a foam stabilizer, 30-50 parts of water and 1-3 parts of sodium tripolyphosphate. The concrete synergist has good workability with a concrete mixture, and has good fluidity and strong bleeding resistance. Through coordination and promotion effects between all components, slurry structure is more compact, and more chemical bonds with stronger binding force are generated between cement hydration particles so as to replace Van der Waals' force. Cementing force of a cementing material is raised, strength of cement and concrete is increased, quality and performance of a concrete material are enhanced, and cohesiveness and pumpability of the concrete mixture are improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a concrete synergist with strong workability and bleeding resistance and concrete thereof. Background technique [0002] Concrete is one of the most used building materials at present, so far, there is no foreseeable material that can replace the application of concrete. However, research data on the degree of cement hydration at home and abroad show that under normal circumstances, about 20-30% of the cement in concrete does not participate in the hydration reaction and does not function normally, which is the biggest waste of cost in concrete applications. Therefore, how to make full use of cement resources has extraordinary significance for realizing energy saving, emission reduction and sustainable development. Synergist is a new type of concrete admixture that has been promoted and used in the construction market in recent years. It can fully disperse cement particles and ...

Problems solved by technology

However, there are some problems in the popularization and application of synergists. After using synergists, some concrete has poor workability, poor fluidity, and rapid loss. There are many types of effect agents, and the product quality is uneven. Like other concrete admixtures, there may be compatibility problems with concrete raw materials such as cement.
