Description
Technical field
The invention discloses a kind of toughening type light aggregate concretes, belong to building material technical field.
Background technique
Light aggregate concrete has many advantages, such as lightweight, durable, energy-saving and environmental protection, in longspan structure engineering such as steel box girder bridge
Face mats formation, skyscraper etc. has broad application prospects, but the intensity of light aggregate concrete and toughness are lower, Practical Project
The strength grade of application is no more than LC50, and fracture toughness index η 30 is less than 15, it is difficult to meet heavy construction, skyscraper to strong
The requirement of degree and toughness, greatly limits the application of light aggregate concrete.The main reason for leading to problem above is
The granule strength of light-weight aggregate itself is lower, and particle is covered with micro-crack easy fracture, and light-weight aggregate itself is porous, quality is soft, in load
Under the action of, stress easily is generated in light-weight aggregate internal void or cracks and is concentrated, and crack extension is caused.And the springform of light-weight aggregate
Measure it is lower, cannot resist deformation and crack extension.For the problem of the above intensity and toughness deficiency, light aggregate concrete is being improved
The technical aspect of intensity is current, and there are mainly two types of methods, and one is add silicon ash in concrete, use high-mark cement, increase
Cement consumption be improve Behavior of Hardened Cement Paste the methods of intensity, such method cost is higher, the contraction of concrete, creep and brittleness increase
Greatly, toughness reduces；Another method is the density of raising light-weight aggregate, thus achieve the purpose that improve light-weight aggregate intensity, though in this way
The intensity of light-weight aggregate so is improved, to improve concrete strength, but the self weight of light-weight aggregate is also increased simultaneously, makes concrete
Density increases.In the technical aspect for increasing high strength lightweight aggregate concrete toughness, mainly realized by adding steel fibre, but these
Although method can effectively improve brittleness, improve toughness, increase rate is limited, mainly itself exists largely due to gathering materials
Micro-crack, bullet mould is lower, easily causes stress to concentrate, leads to crack propagation and be broken, limit the toughening effect of steel fibre, and
The workability of concrete can be reduced, meanwhile, steel fibre volume cross the self weight that conference improves light aggregate concrete, and steel fibre meeting
The performance of light aggregate concrete is greatly lowered because corrosion occurs, concrete is caused to destroy.Use high-strength lightweight
Although the intensity of concrete can be effectively increased, the granule strength of current high-strength lightweight mainly in 6.0~8.0MPa, and
It is covered with fine crack, so being difficult to make high tenacity, high strength light aggregate concrete.Light aggregate concrete traditional at present is anti-
Compressive Strength and the bad problem of toughness, therefore also need to study it.
Summary of the invention
The present invention solves the technical problem of：It is asked for traditional light aggregate concrete compression strength and toughness are bad
Topic, provides a kind of toughening type light aggregate concrete.
