Abstract
The invention discloses a high-strength high-performance concrete which is prepared from poly(dimethyl carboxylate), sodium tripolyphosphate, a naphthalene-based superplasticizer, sand, cobblestone and cement. According to the invention, common materials in a variety of mix ratios are used and considerable concrete tests are carried out so as to obtain the high-strength high-performance concrete with strength grades of C80, C90 and C100, and the high-strength high-performance concrete has high strength and good endurance and can be used for a variety of high-rise large-span projects constructed in severe conditions and environments.
Description
Technical field
The present invention relates to build to build use the strong concrete technical field, specifically a kind of high-strength high-performance concrete.
Background technology
In the at present construction work, the crack of concrete structure is comparatively general, concrete shrinks in knot hard process, can expand with heat and contract with cold during temperature variation, after these two kinds of distortion suffer restraints, will produce string stress in inside configuration causes concrete cracking and forms shrinkage crack, along with building to maximizing and multi-functional development, overlength (namely surpassing the Temperature Joint spacing) high level or large column net building constantly occur, the raising of strength grade of concrete, the application of pumped concrete earth process in the construction, there is the trend that increases gradually in the temperature shrinkage crack that Overlong Concrete Structure is prone to, affects weather resistance and the globality of structure.
Summary of the invention
Purpose of the present invention provides a kind of high-strength high-performance concrete for overcoming the deficiencies in the prior art.
In order to achieve the above object, the present invention has designed a kind of high-strength high-performance concrete, is prepared from by poly carboxylic acid series mixture, tripoly phosphate sodium STPP, naphthalene series high-efficiency water-reducing agent, sand, stone, cement; Described component is respectively: polydimethyl carboxylicesters 100-200kg, tripoly phosphate sodium STPP 20-50kg, naphthalene series high-efficiency water-reducing agent 15-30kg, sand 500-800kg, stone 1200-2300kg, cement 1000-1500kg.
Described naphthalene series high-efficiency water-reducing agent accounts for the 2%-3% of overall concrete quality, and its water-cement ratio is 0.2-0.35.
The tripoly phosphate sodium STPP that contains different amounts in the concrete of described different grades.
Described polydimethyl carboxylicesters is the agent on crack resistance of concrete separate ingredient.
Advantage of the present invention is: utilize popular material, by various mixing proportion design methods and a large amount of concrete test, having drawn strength grade is the high-strength high-performance concrete of C80, C90, C100, intensity is high, good endurance, can be used for the various engineerings under high level, large span and the mal-condition environment.
Embodiment
Now the present invention will be further described in conjunction with the embodiments.
Example 1: get polydimethyl carboxylicesters 100kg, tripoly phosphate sodium STPP 20kg, naphthalene series high-efficiency water-reducing agent 15kg, sand 500kg, stone 1200kg, cement 1000kg mix and blend is made the high-strength high-performance concrete that strength grade is C80.
Example 2: get polydimethyl carboxylicesters 150kg, tripoly phosphate sodium STPP 35kg, naphthalene series high-efficiency water-reducing agent 20kg, sand 600kg, stone 1800kg, cement 1300kg mix and blend is made the high-strength high-performance concrete that strength grade is C90.
[0011] example 3: get polydimethyl carboxylicesters 200kg, and tripoly phosphate sodium STPP 50kg, naphthalene series high-efficiency water-reducing agent 30kg, sand 800kg, stone 2300kg, cement 1500kg mix and blend is made the high-strength high-performance concrete that strength grade is C100.
