Abstract
The invention discloses a lightweight concrete. The lightweight concrete comprises, by mass, 60-80 parts of water, 20-30 parts of cement, 40-50 parts of PC, 200-300 parts of cobblestones, 100-120 parts of river sands, 10-15 parts of quicklime, 1-2 parts of a foaming agent and 3-5 parts of an additive. The lightweight concrete has the advantages of light weight, small slump loss, good fluidity, energy saving and environmental protection.
Description
Technical field
The present invention relates to concrete field, particularly relate to a kind of lightweight concrete.
Background technology
Concrete refers to be cemented to gathering materials the general designation of the engineered composite material of entirety by Binder Materials.Concrete one word generally said refers to make Binder Materials with cement, and sand, masonry gather materials；Coordinating by a certain percentage with water (adding or be not added with additive and admixture), cement concrete, also referred to as normal concrete obtained by agitated, molding, maintenance, it is widely used in civil engineering.Lightweight concrete is that a kind of profit is useless, environmental protection, energy-conservation, cheap and have non-flame propertiesNovelEnergy-saving building materials.Lightweight concrete (foam concrete) is to need to introduce in concrete mortar by gases such as air or nitrogen, carbon dioxide, oxygen according to application by the way of chemically or physically, through reasonable maintenance molding, and formed containing the most tiny sealed porosity, and there is the concrete product of suitable intensity.But, existing concrete is big due to weight, causes powerful burden to construction；It addition, the water reducer that existing concrete uses so that the loss of slump of concrete is very big, poor fluidity.
Summary of the invention
The technical problem to be solved is to provide that a kind of energy-conserving and environment-protective, loss of slump be little, the lightweight concrete of good fluidity.
A kind of lightweight concrete of the present invention, including the material of following mass fraction: water: 60-80, cement: 20-30, PC:40-50, cobblestone: 200-300, river sand: 100-120, quick lime: 10-15, foaming agent: 1-2, additive: 3-5.
Improving further, described lightweight concrete includes the material of following mass fraction: water: 70, cement: 25, PC:45, cobblestone: 250, river sand: 110, quick lime: 12.5, foaming agent: 1.5, additive: 4.
Improving further, described additive is polycarboxylate water-reducer.
Improving further, described foaming agent is CBA.
Improving further, described CBA is inorganic foaming agent.
Improving further, described inorganic foaming agent is one or more in calcium carbonate, aluminium carbonate, sodium bicarbonate.
The beneficial effects of the present invention is:
Lightweight concrete of the present invention, break traditions the formula of concrete, PC is replaced part of cement, activation through calcium carbonate, and the reinforcement of quick lime, gained Lightweight concrete not only has the construction value of concrete, and quality to alleviate more than 15 times than existing concrete, alleviates the biggest burden to construction；Employing cobblestone is raw material, by increasing foaming agent and the lightweight concrete of additive formation environmental protection and energy saving, and effectively make use of resource；High performance water reducing agent of polyocarboxy acid water-reducing rate is high, it is possible to decrease concrete water amount, saves cement, keeps the ratio of mud constant, also can improve intensity, it addition, apply this water reducer, the loss of slump of concrete can be reduced, keep concrete to have a good mobility, be suitable for configuration high-strength concrete.
Detailed description of the invention
The present invention is described in further detail below:
Embodiment 1:

Embodiment 2:
The present invention provides a kind of lightweight concrete, including the material of following mass fraction: water: 70, cement: 25, PC:45, cobblestone: 250, river sand: 110, quick lime: 12.5, foaming agent: 1.5, additive: 4.
Embodiment 3:
The present invention provides a kind of lightweight concrete, including the material of following mass fraction: water: 60, cement: 20, PC:40, cobblestone: 200, river sand: 100, quick lime: 10, foaming agent: 1, additive: 3.
Embodiment 4:
The present invention provides a kind of lightweight concrete, including the material of following mass fraction: water 80, cement: 30, PC:50, cobblestone: 300, river sand: 120, quick lime: 15, foaming agent: 2, additive: 5.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to make some improvement, and these improvement also should be regarded as protection scope of the present invention.
