Abstract
Related high-strength concrete comprises the compositions in parts by weight: 220-240 parts of cement, 400-450 parts of fine aggregate, 40-80 parts of composite ultrafine powder, 3-6 parts of a retarder, and 50-60 parts of water. The high-strength concrete employing the above design is large in strength, is applicable to tall buildings, and is strong in shock resistance.
Description
Technical field
The present invention relates to concrete field, especially a kind of strong concrete.
Background technology
Along with the development of modernization Highrise buildings and longspan structure, more and more higher to the requirement of concrete strength, adopt the sectional dimension that high-strength concrete can significantly reduce, alleviate the deadweight of works, also make the labor capacity of workmen, Energy Consumption of Construction and raw-material consumption etc. reduce greatly, the corresponding increase of effective usable floor area of buildings, shock resistance is improved, and therefore, uses high-strength concrete to have apparent Technical Economy and social benefit.
The configuring technical of strong concrete is complicated, production difficulty is larger, the many factors of impact preparation and use high-strength concrete, as to raw-material selection, the quality of admixture and Additive, the requirement of mix-design and production unit and technology controlling and process etc. is very high, obtain high-strength concrete, and all just must be taked may to improve the advantageous measures of concrete strength.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome above-mentioned middle Problems existing, provide a kind of strong concrete.
The technical solution adopted for the present invention to solve the technical problems is: a kind of strong concrete, comprises and being mixed by cement, fine aggregate, coarse aggregate, composite ultrafine powder, retardant and water, and its weight part consists of: cement 220 ~ 240 parts; Fine aggregate 400 ~ 450 parts; Composite ultrafine powder 40 ~ 80 parts; Retardant 3 ~ 6 parts; 50 ~ 60 parts, water.
Described cement is 52.5MPa level silicate cement.
Described coarse aggregate is granite stones, and its particle diameter is 31.5mm.
Described composite ultrafine powder is mixed by flyash and slag, and the ratio of flyash and slag proportioning is 6:4.
Described retardant is water reducer.
The invention has the beneficial effects as follows: described a kind of strong concrete, adopt the concrete of this kind of design, its intensity is large, and can be applied to high building, shock resistance is strong.
Embodiment
Be described in further detail in conjunction with the present invention now.
A kind of strong concrete of the present invention, comprises and being mixed by cement, fine aggregate, coarse aggregate, composite ultrafine powder, retardant and water, and its weight part consists of: cement 230 parts; Fine aggregate 430 parts; Composite ultrafine powder 60 parts; Retardant 5 parts; 55 parts, water, cement is 52.5MPa level silicate cement, and coarse aggregate is granite stones, and its particle diameter is 31.5mm, and composite ultrafine powder is mixed by flyash and slag, and the ratio of flyash and slag proportioning is 6:4.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification sheets, must determine its technical scope according to right.
