Abstract

The present invention relates to technical field of concrete, specifically disclose a kind of underwater concrete formula, are made from the following raw materials in parts by weight:1200~1900 parts of cement, 2500~3500 parts of river sand, 500~650 parts of rubble, 700~1000 parts of water, outer ginseng expect 200~450 parts, 180~300 parts of additive.The present invention overcomes the deficiencies in the prior art, have good cast smoothness, the good stability for resisting bleeding and separation, cast is convenient, and construction cost is low.

Description

A kind of underwater concrete formula
Technical field
The present invention relates to technical field of concrete, particularly belong to a kind of underwater concrete formula.
Background technology
Locate progress mixing doing, and the concrete for pouring and hardening under water, it is called underwater concrete.Concrete is under water Although can be with setting and hardening, pouring quality be poor.Therefore, only in the case that unavoidable, or in some secondary structures Underwater portion, the method for just taking underwater casting.It is more demanding to concrete placed under water, it is necessary to have not detach under water The characteristics such as property, self compacting ability, low bleeding and slow setting.
Concrete placed under water is carried out, mix avoided contacting with ambient water before entering storehouse surface;Into after storehouse surface, The concrete contacted with water is contacted with water always.That pours afterwards no longer contacts with water, it is desirable that concrete should have enough mobility To resist the stability of bleeding and separation and it is necessary to be carried out in the cofferdam that can really prevent flowing water from influencing.Must not pour and interrupts And it should carry out as quickly as possible.Interior for 24 hours after the completion of pouring, cofferdam must not draw water.
Invention content
The object of the present invention is to provide a kind of underwater concrete formulas, overcome the deficiencies in the prior art, have Good cast smoothness, the good stability for resisting bleeding and separation, cast is convenient, and construction cost is low.
To solve the above problems, the technical solution used in the present invention is as follows:
A kind of underwater concrete formula, is made from the following raw materials in parts by weight:1200~1900 parts of cement, river sand 2500~ 3500 parts, 500~650 parts of rubble, 700~1000 parts of water, outer ginseng expect 200~450 parts, 180~300 parts of additive.
Further, it is made from the following raw materials in parts by weight:1500 parts of cement, 3000 parts of river sand, 550 parts of rubble, water 800 Part, outer ginseng expect 350 parts, 210 parts of additive.
Further, the additive is water-reducing agent.
Further, the extra material is coal ash, and four degree of the coal ash is 6.6%, loss on ignition 0.94%, water demand ratio 88%.
Further, the cement is portland cement.
Compared with prior art, implementation result of the invention is as follows by the present invention:
A kind of underwater concrete formula of the present invention has good cast smoothness, good resistance bleeding and divides From stability, cast is convenient, and construction cost is low.
Specific implementation mode
With reference to embodiment, the invention will be further described, but the present invention is not limited to these instances, and is being de- Under the premise of from present inventive concept, carried out by it is any improvement be within the scope of the present invention.
