Abstract
The invention relates to an underwater grouting agent of concrete that adds 0.033-0.1% polyacrylamide into the engineering concrete made from concrete, sand, stone, fly ash and water. It could directly take underwater grouting and reach C30 intensity level.
Description
Technical field
The present invention relates to a kind of cement concrete material that is used for underwater construction.
Background technology
When general normal concrete directly watered under water, because the influence of water produces and separates, cement ran off, strength degradation, contaminate environment.Therefore, when carrying out concrete construction under water, usually adopt the water proof method, promptly improve, concrete mix is reduced or stop to contact, thereby avoid the influence of water with water from service tool, solve the pouring and the quality problems of concrete in water, consequently make construction technology complicated, engineering cost increases greatly, and is difficult to guarantee the quality of concrete in water.Be head it off, people have developed non-dispersible underwater concrete.The gordian technique of preparation non-dispersible underwater concrete is to add a kind of special admixture in concrete mix.Various admixtures respectively have characteristics, but most complicated process of preparation discloses a kind of modified polyacrylamide for concrete keeping together underwater flocculation agent as CN1480475, is exactly this situation, cause engineering cost to be difficult to descend.
Summary of the invention
The objective of the invention is to propose a kind of low cost, be easy to prepare the dispersive cement concrete underwater grouting material not under water of construction.
The underwater grouting material of cement concrete proposed by the invention is to add the polyacrylamide that accounts for slurry material gross weight 0.33 ‰～1 ‰ to be mixed and to form in the engineering concrete grout material by cement, sand, stone, flyash and water preparation.
The underwater grouting material set of dispense ratio of the preferred cement concrete of the present invention is: every cube of slurry material contains:
Cement 301kg,
Sand 781kg,
Stone 1054kg,
Flyash 74kg,
Polyacrylamide 7.9kg,
Water 180kg,
Described cement is 32.5R or 42.5R silicate cement.
The preparation method of the underwater grouting material of cement concrete of the present invention is, earlier with polyacrylamide and cement by polyacrylamide: the part by weight of cement=1: 1 is mixed, the material that is mixed with described polyacrylamide and cement before construction adds in the engineering concrete grout material, stir, the polyacrylamide in the material accounts for slurry material gross weight 0.33 ‰～1 ‰.
The underwater grouting material of the cement concrete that the present invention prepared is met water and is not emanated, and cement does not run off, and can directly water construction under water, and this material can reach the strength grade of C30～C40.The underwater grouting material blending process of cement concrete of the present invention is simple, can save construction investment greatly, has significant technical economic benefit.
Embodiment
Embodiment
The underwater grouting material set of dispense ratio of this cement concrete is: every cube of slurry material contains:
Cement 301kg,
Sand 781kg,
Stone 1054kg,
Flyash 74kg,
Polyacrylamide 7.9kg,
Water 180kg,
Cement adopts the silicate cement of 42.5R.
The underwater grouting material compound method of this cement concrete is as follows, earlier polyacrylamide and etc. the cement of weight be mixed, other components (cement, sand, stone, flyash and water) are mixed with engineering concrete grout material, before watering construction under water, the material that is mixed of polyacrylamide and cement is added in the engineering concrete grout material, stir.
This material waters in the 1# dock improvement project of Guangzhou Shipbuilding International under water, reaches the strength grade of C30.
