Description

A kind of preparation method of high-performance pile tube
Technical field
The present invention relates to a kind of preparation method of high-performance pile tube, belong to building material manufacture field.
Background technology
The raw-material volume of volume ratio reacting the crystalline compound formed due to water and cement is little, therefore causes the contraction of volume of concrete.In morning, the mid-term of sclerosis, cause drying shrinkage, temperature variation etc. due to the evaporation of free water in concrete again, this series of problem causes concrete easy to crack.Cement expansive material is a kind of mineral additive, has the effect of anti-crack and anti-seepage, and it generates ettringite, calcium hydroxide and magnesium hydroxide through hydration reaction after mixing and stirring with cement, water in concrete mixing process, makes concrete produce volumetric expansion.Be called expansive concrete with the concrete of its preparation, apply at home widely at present, positive effect is served to the quality improving concrete construction.Use cement expansive material can prepare expansive concrete, fill concrete, filling mortar, self-stressing concrete and water-proof concrete.At China's swelling agent by a large amount of for expansive concrete, expansive concrete is reacted by expansion component and hydrolysis product of cement to produce volumetric expansion, by expansion energy to restraint work done, the confined expansion produced is offset concrete drying, cooling and load etc. and is acted on the confined shrinkage caused, generally inside concrete can be made to set up the stress of 0.2-0.7MPa under used arrangement of reinforcement condition, mainly dry shrinkage be compensated.The key distinction of expansive concrete and normal concrete is: 1. due to the effect of confined expansion, improves concrete stressed condition; 2., because the filling effect of swelling property crystal makes the macropore in Behavior of Hardened Cement Paste diminish, overall porosity declines, and improve concrete pore structure, thus improve concrete impermeability, it has the crack resistance that general water-proof concrete cannot be compared.
We find a kind of to be used for concrete additive in test of long duration and practice, concrete additive of the present invention in intensity, toughness, stability etc. on performance excellent, be specially adapted to road, bridge.And by adding this concrete additive, make the effect that concrete surface is smooth, have obvious brightness.
