High-adaptability glue reducing agent for concrete
The invention discloses a high-adaptability glue reducing agent for concrete. The high-adaptability glue reducing agent for concrete is prepared from, by weight, 20-45% of alcohol and amine compounds, 10-20% of melamine water reducing agents, 5-20% of silica sol, 1-5% of alcohol and aldehyde compounds, 0.1-0.5% of alkali-resistant permeation agents and the balance water. When the high-adaptability glue reducing agent, polycarboxylate, naphthalene and aliphatic series water reducing agents are compounded for use, the rheological property of cement-based cementing material mixtures is slightly improved, and the workability of the mixtures is improved. The alcohol and aldehyde compounds and the alcohol and aldehyde compounds in the components of the high-adaptability glue reducing agent for concrete can have a synergetic dispersion effect on C3A and C4AF quick-hardening mineral phases, the hydration speed and process of C3S and C2S main mineral phases can be further stimulated by the silica sol, the melamine water reducing agents supplement part of the water reducing effect, it is guaranteed that early-stage strength reaches the standard, and the alkali-resistant permeation agents can certainly improve the permeation effect of surfactants in an assistance mode.
