Abstract

The invention discloses a water-reducing agent containing peanut shell powder. The water-reducing agent containing peanut shell powder is prepared by mixing the following raw materials in parts by weight: 30-50 parts of aromatic sulfamate formaldehyde condensate, 15-25 parts of sodium methylene bis-naphthalene sulfonate, 5-10 parts of 2-ethylhexyl phosphate, 10-15 parts of abitol polyoxyethylene ether monosulfosuccinate, 8-12 parts of fluoroplast, 10-15 parts of polyethyleneimine, 3-5 parts of erucamide, 4-8 parts of 8-hydroxyquinoline potassium sulfate, 3-6 parts of peanut shell powder, 5-10 parts of sea mud, 10-15 parts of waste mortar, 5-10 parts of collagen freeze-dried powder, 8-12 parts of sodium pyrrolidonecarboxlate, 5-10 parts of polyamide-epichlorohydrin resin, and 4-8 parts of auxiliaries. The water-reducing agent is high in water reducing rate which is up to more than 20%, excellent is plasticity retention property, good in cement adaptability, convenient to use, free from influence on properties by being directly doped into concrete, capable of improving the mobility, anti-seepage property and durability of the concrete, and wide in the range of application.

Description

technical field [0001] The invention relates to a water reducer containing peanut shell powder, belonging 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 water reducer is the most important admixture in concrete. It can reduce the mixing water consumption and improve the concrete strength under the condition that the workability of concrete and the amount of cement remain unchanged; or under the condition that the workability and strength remain unchanged. Next, save the amount of cement. However, th...
