The grouting material is characterized by comprising the following components in part by weight: 380 to 440 parts of cement, 520 to 580 parts of sand, 35 to 50 parts of expanding agent, 2.8 to 3.2 parts of water reducing agent, 1.6 to 2.0 parts of foam suppressor and 1.0 to 2.0 parts of melamine, wherein the cement is of Conch cement P.042.5 or P.052.5 ordinary Portland cement; the sand is of river sand and the particle size of the medium sand is of between 0 and 3.2mm; the expanding agent is of a UEA concrete expanding agent; the foam suppressor is of a YAMASO DF654 foam suppressor; the water reducing agent is of an FDN-C high-efficiency water reducing agent; and the melamine is sulphonated melamine.
Description
Technical field
The foundation works that the present invention relates to a kind building material field specifically, is a kind of minimizing grouting material bleeding with the grouting material, increases homogeneity, and has the large-flow grouting material of rolling mill for foundation engineering than high flowability.
Background technology
For guaranteeing the installation and debugging of equipment, when the cast basis, adopt thin real concrete to tamp the back-grouting layer usually.Grouting has high workability, and advantages of high strength more and more is used in engineering construction.But existing grouting material in use, and degree of mobilization makes the grouting material can not be full of whole space inadequately, many spaces occur, even grouting cavernes; And grouting material adds and all can bubble after water stirs, and has the space between plant bottom case and the grout blanket like this, thereby influences the density of itself and plant bottom case.
The base area of husky steel engineering milling equipment is bigger, planar dimension is 1.8m * 2.2m, after having tried out multiple grouting material, all can't fill the entire equipment base, degree of mobilization only is 260-280mm, be that its degree of mobilization does not reach requirement, so iron and steel enterprise's engineering milling equipment base press for the grouting material that has than high flowability.
Summary of the invention
Purpose of the present invention is to propose a kind of grouting material bleeding that reduces in construction, increase homogeneity, and have the large-flow grouting material of rolling mill for foundation engineering than high flowability.
For achieving the above object, technical solution of the present invention is:
A kind of large-flow grouting material of rolling mill for foundation engineering, it is characterized in that: described grouting material package is drawn together the cement of 380-440 weight part, the sand of 520-580 weight part, the swelling agent of 35-50 weight part, 2.8-3.2 the water reducer of weight part, 1.6-2.0 the suds suppressor of weight part, the melamine of 1.0-2.0 weight part is characterized in that:
Described cement is P.042.5 or P.052.5 ordinary Portland cement of conch cement;
Described sand is river sand, and the medium sand particle diameter is between 0mm-3.2mm;
Described swelling agent is the UEA cement expansive material;
Described suds suppressor is a YAMASO DF654 suds suppressor;
Described water reducer is the FDN-C high efficiency water reducing agent;
Described melamine is a sulfonated melamine.
Large-flow grouting material of rolling mill for foundation engineering of the present invention can also be further achieved by the following technical measures.
Aforesaid grouting material, the presetting period 〉=45min of wherein said UEA cement expansive material, final set≤10h, limited expansion rate in air 21 days 〉=-0.02,7 days intensity 〉=25.0mpa, 28 days intensity 〉=45.0mpa).
Aforesaid grouting material, the slurry water-reducing rate of wherein said DN-C high efficiency water reducing agent is 29.2%.
Aforesaid grouting material, wherein said sulfonated melamine are the SM-F high efficiency water reducing agents, and the slurry water-reducing rate is 20.2%, flowing degree of net paste of cement 240.
After adopting technique scheme, large-flow grouting material of rolling mill for foundation engineering of the present invention has the following advantages:
1. it is non-foaming to reach the grouting material, thereby has increased the density between plant bottom case and the grout blanket.
2. strengthen the degree of mobilization of grouting material, make its degree of mobilization reach 300～320mm.
