Abstract
The invention relates to a preparation method of a concrete waterproofer which is mainly applied to the field of the architecture industry, and concretely relates to the preparation method of the concrete waterproofer with an industrial by-product gysum non-calcining technology. The preparation method comprises the following steps: carrying out simple dehydration on the industrial by-product gysum until water content is below 10%; preparing material powder with diameters of less than 200 meshes by modifying through a Raymond mill; mixing the industrial by-product gysum powder, semihydrated gypsum, alum and kaolin according to a proportion of 3-5:0.5-2:2-4:1-3; and ball milling to the fineness of less than 200 meshes. The concrete waterproofer prepared in the present invention has a high efficient water-reducing and reinforcing function, allows the pore structure of the concrete to be effectively improved and gel to be precipitated simultaneously to block capillary channels in the concrete, so the impermeability is improved 5 to 8 times compared with conditions with no waterproofers, the waterproof effect is permanent, the heat release rate of cement hydration can be delayed, concrete cracking can be effectively prevented, and 10% of cement can be saved.
Description
Technical field
The present invention relates to a kind of preparation method of concrete waterproofer, be mainly used in the construction industry field, specifically relate to a kind ofly exempt from the method that calcining technology prepares concrete waterproofer with industry by-product gypsum.
Background technology
2009, about 1.18 hundred million tons of China's industry by-product gypsum generation, comprehensive utilization ratio is merely 38%.Wherein, about 4,300 ten thousand tons of desulfurated plaster, comprehensive utilization ratio about 56%; About 5,000 ten thousand tons of phosphogypsum, comprehensive utilization ratio about 20%; About 2,500 ten thousand tons of other by-product gypsums, comprehensive utilization ratio about 40%.The volume of cargo in storage of industry by-product gypsum accumulation at present surpasses 300,000,000 tons, and wherein, desulfurated plaster is more than 5,000 ten thousand tons, and phosphogypsum is more than 200,000,000 tons.Industry by-product gypsum is stored up in a large number, and both land occupation was wasted resource again, and acid and other objectionable impuritiess that contain pollute surrounding enviroment easily, have become the important factor of restriction China's coal-firing units gas desulfurization and phosphatic fertilizer company Sustainable development.
Summary of the invention
In order to solve the problems of the technologies described above; The object of the present invention is to provide a kind of a large amount of industry by-product gypsums that consume; Industry by-product gypsum is processed into have waterproof, slow setting, the method for the inorganic materials of effects such as strong, diminishing, cracking resistance early, promptly exempt from the method that calcining technology prepares concrete waterproofer with industry by-product gypsum.
The technical scheme that the present invention adopts is following:
Exempt from the method that calcining technology prepares concrete waterproofer with industry by-product gypsum, may further comprise the steps:
1., with industry by-product gypsum simple dehydrating to water cut below 10%, and utilize the Raymond mill modification, process the above powder of 200 orders;
2., industry by-product gypsum powder, semi-hydrated gypsum, alum and kaolin are pressed 3-5: the mixed of 0.5-2: 2-4: 1-3, ball milling to fineness are more than 200 orders, make product.
Preferred version may further comprise the steps:
1., with the industry by-product gypsum simple dehydrating to water cut 8%-10%, and utilize the Raymond mill modification, process 250-300 purpose powder;
2., industry by-product gypsum powder, semi-hydrated gypsum, alum and kaolin were pressed 4: 1: 3: 2 mixed, ball milling to fineness is the 250-300 order, makes product.
The concrete waterproofer of the present invention's preparation has diminishing, enhancement function efficiently, can effectively improve concrete pore structure; Separate out gel simultaneously, stop up the inside concrete capillary porosity duct, and do not add water-resisting agent and compare; Anti-permeability performance can improve 5-8 doubly, has the permanent water-resistant effect, can delay the hydrated cementitious rate of heat release; Concrete cracking can be effectively prevented, cement 10% can be saved.In addition, the present invention carries out the grinding machine modification then directly with the industry by-product gypsum simple dehydration, does not have thermal treatments such as calcining, and energy-saving and emission-reduction, utilization of waste material are had stronger social effect.
Embodiment
Below in conjunction with embodiment the present invention is further described; It should be noted that; Embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage that is familiar with this art can understand content of the present invention and also implements, and can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Embodiment
With industry by-product gypsum simple dehydrating to water cut 8%, and utilize the Raymond mill modification, process powder, cross 250 mesh sieves.
40kg industry by-product gypsum powder, 10kg semi-hydrated gypsum, 30kg alum and 20kg kaolin are mixed, and ball milling to fineness is 250 orders, can make concrete waterproofer.
