Abstract

The invention discloses an early-strength waterproof agent for ordinary Portland cement. The early-strength waterproof agent is prepared from the following raw materials in parts by weight: 100 to 300 parts of calcium sulfate, 5 to 10 parts of sodium tripolyphosphate, 100 to 300 parts of sodium hydroxide, 5 to 10 parts of stearic acid, 0.5 to 1 part of potassium aliphatate, 0.2 to 0.5 part of macadamia oil, 0.1 to 0.3 part of linolenic acid, 0.2 to 0.6 part of hydrogenated rosin, 0.2 to 0.4 part of animal glue and 10 to 20 parts of kieselguhr. The early-strength waterproof agent disclosed by the invention is non-toxic and non-pollution, matters or gases which are toxic and harmful to a human body or the environment cannot be generated, and the early-strength waterproof agent is relatively green and environment-friendly during a using process; meanwhile, the early-strength waterproof agent is capable of quickly promoting the early strength of the ordinary Portland cement, and the waterproof performance is excellent.

Description

technical field [0001] The invention relates to an early-strength waterproofing agent, in particular to an early-strength waterproofing agent for ordinary Portland cement. Background technique [0002] Concrete early strength agent is one of the earliest admixture varieties used in the history of admixture development. So far, people have developed a variety of early-strength admixtures other than chloride and sulfate, such as nitrite, chromate, etc.; and organic early-strength agents, such as triethanolamine, calcium formate, urea, etc. And on the basis of the early strength agent, a variety of composite admixtures are produced and applied, such as early strength water reducer, early strength antifreeze and early strength pumping agent. Although the early strength agent has a long history of production and application, with the deepening of people's understanding of the potential hazards of chloride ions, sulfate ions, nitrate ions and alkali metal ions to concrete perform...
