Abstract

The invention discloses a formula of a composite liquid cement grinding aid, comprising the following components by weight percentage: 5-30% of triethanolamine, 5-25% of triisopropanolamine, 1-20% of polyols, 1-10% of sodium hexametaphosphate, 0.1-1% of a surface active agent, 0-0.5% of a PH regulator and the balance of water. The preparation method of the composite liquid cement grinding aid comprises steps of: adding sodium hexametaphosphate into a closed container containing water with stirring; after complete dissolution of the sodium hexametaphosphate, successively adding triethanolamine, triisopropanolamine, polyols and the surface active agent, and continuing to stir for 15-20 min; and controlling the pH value of the solvent at 7.5-8.5, and standing for 30-40 min. The formula and preparation method of the composite liquid cement grinding aid disclosed by the invention have advantages of simple production process, wide adaptability, good adaptability with concrete admixtures, and capability to improve the flexural strength and compressive strength of cement.

Description

technical field [0001] The invention relates to a cement grinding aid formula and a preparation method thereof, in particular to a compound liquid cement grinding aid formula and a preparation method thereof. Background technique [0002] Cement plays an extremely important role in today's ever-changing urbanization construction. It is a powdery hydraulic inorganic gelling material that can be hardened in air or water after being stirred into a slurry with water. The material is cemented into mortar or concrete. The finer the fineness of the cement, the faster the hydration and hardening reaction, the easier the hydration is, the higher the effective utilization rate of the cement gelling properties, the higher the strength of the cement, especially the early strength, and it can also improve Bleeding and workability of cement. On the contrary, if there are too coarse grains in the cement, the coarse grains can only react on the surface, thus losing the activity of clinker...
