Abstract

The invention discloses an early-strength water reducer, which comprises the following raw materials by weight: 36-48 parts of benzyl naphthalene sulfonate formaldehyde condensate, 14-22 parts of polyacrylamide, 25-35 parts of methylene dimethyl binaphthol sulfonate polymer, 12-16 parts of asphalt, 5-10 parts of nano zirconium carbide, 7-14 parts of precipitated barium sulphate, 4-8 parts of urea, 10-15 parts of bentonite, 5-10 parts of silica fume, 5-10 parts of earthy graphite powder, 3-6 parts of calcium formate, 2.5-4.5 parts of sodium hyposulfite, 4-7 parts of phosphogypsum, 8-12 parts of polyester propylene glycol, 4-8 parts of paper pulp waste liquid and 3-5 parts of auxiliary agent. The early-strength water reducer has good early strength, water reduction and enhancement effects, the water reduction rate is large, concrete strength at early stage and anaphase can be obviously increased, frost resistance, impermeability and endurance performance of the concrete can be enhanced, and the early-strength water reducer has good adaptability to cement types, and accords with a national standard of a concrete additive.

Description

technical field [0001] The invention relates to an early-strength water reducer and belongs to the field of concrete admixtures. Background technique [0002] Concrete admixtures, referred to as admixtures for short, refer to substances that are added to improve the performance of concrete before or during the mixing of concrete. Because admixtures can effectively improve the performance of concrete and have good economic benefits, they have been widely used in many countries, and their application in engineering has attracted more and more attention, becoming an indispensable material in concrete. Among them, the early-strength water-reducing agent is one of the concrete admixtures, which can promote the hydration and hardening of the cement, shorten the maintenance period of the concrete products, speed up the construction speed, and increase the turnover rate of the formwork and the site. The early-strength superplasticizers currently used in the market have the disadvan...
