Description
Technical field
The present invention relates to a kind of building concrete material and compound method thereof.
Background technology
Along with the development of urban construction and the progress of operating technique, concrete quality parameter and economic target are had higher requirement, promote that concrete develops towards high-strength, lightweight, fluidised form, durable contour performance direction.
Especially over past ten years, because the development of efficient additive and concrete admixture technology,, high performance concrete high-strength for preparation under the ordinary process condition provides favourable technical qualification.In some large scale structures, railway engineering and the public works design, the concrete that C50, C60 label have occurred morely, the C100 high performance concrete also is the focus that domestic and international concrete material is studied over year surplus in the of nearly ten, all drops into a large amount of human and material resources and financial resources both at home and abroad this is studied.In general, existing C 100 high performance concrete compounding processs are as follows:
Under the situation that does not change the various raw material ratios (dewatering) and the concrete slump, reduce the consumption of water, can improve concrete intensity greatly, early strong and later strength improves more than 60% and 20% than the concrete that does not add water reducer respectively, by diminishing, can realize building the high-strength concrete of C100 label.
High efficiency water reducing agent commonly used has following several: naphthalenesulfonate formaldehyde condensation compound, polycyclic aromatic hydrocarbon sulfonate formaldehyde condensation products, melamine sulfonate and formaldehyde polycondensate, para-anilinesulfonic acid formaldehyde condensation products, sulfonated ketone aldehyde polycondensate, polyacrylate and graft copolymer thereof etc.

3～700kg/m
3
In order to save cement consumption, concrete admixture commonly used has silica flour isoreactivity mineral spike.
The exciting agent that the mineral spike is commonly used has three classes: I type exciting agent is to mix industrial mineral alkali (A) 3%; II type exciting agent is to mix industrial mineral alkali (A) 3% and vitriol (B) 2%; III type exciting agent is to mix mineral alkali 2% and vitriol (B) 3%.
The technical problem that the C100 high performance concrete is badly in need of solving has following four:
1, because non-common starting material and unconventional production technique such as employing cement of high index make the manufacturing cost of C100 high performance concrete higher relatively.
2, when increasing substantially concrete strength, can not realize improvement and raising to workability of concrete energy and endurance quality.
3, owing to Beijing area aggregate material reason and consolidating material cohesive strength deficiency, be difficult to make the C100 high performance concrete.
4, the C100 high performance concrete moves towards the heavy construction application by testing laboratory and is still waiting realization.
Summary of the invention
The purpose of this invention is to provide a kind of C100 high performance concrete and compound method thereof, solving existing C100 high performance concrete preparation needs special source materials such as cement of high index, complex manufacturing, problem that manufacturing cost is high; And solve when increasing substantially concrete strength, improve the technical problem of workability of concrete and weather resistance.

The solid content of above-mentioned high-efficiency water-reducing agent of poly-carboxylic acid is 18%～30%, and water-reducing rate is 30%～45%.
Above-mentioned 42.5 cement are normal silicate 42.5 cement or silicate 42.5 cement.
Silica flour, flyash and three kinds of components of slag powders are arranged in the above-mentioned adulterant, and the weight ratio of above-mentioned three kinds of components is: 1: (1～3): (1～3).
The specific surface area of above-mentioned exciting agent is 600 ± 50m
2/ kg contains the cigarette ash that accounts for gross weight 5070% and 3050% coal gangue fine powder in the mixture.
Above-mentioned C100 high performance concrete is characterized in that every cubic metre mixing ratio by weight is:
Water-cement ratio (water/gelling material): 0.24-0.28;
Sand coarse aggregate ratio: 34-40%;
Cement: 400-500kg/m

The compound method of above-mentioned C100 high performance concrete is characterized in that following steps are arranged: sand, stone, cement, adulterant, admixture are put into forced mixer simultaneously stirred for 5 seconds, add restir discharging in 180 seconds behind the water.
The preparation strength of C100 high performance concrete can be by " design of common concrete proportioning technical regulation " regulation (JGJ/T55-1996), as calculated, examination join, adjust come definite.Preparation strength f
Cu, oFor: f
Cu, o=f
Cu, k-1.645
In the formula: f
Cu, o-high performance concrete preparation strength (MPa)
f
Cu, kThe standard value of-high performance concrete (MPa)
The standard deviation of σ-high performance concrete (MPa)
As no data, when design strength was C100, σ got 6Mpa.
After proportioning is determined, still use the revision test that this proportioning is no less than 6 times and verify that its mean value should not be lower than preparation strength.
