Description
Technical field
The present invention relates to building material technical field, more particularly to a kind of concrete containing quartz sand.
Background technology
Concrete, referred to as " concrete（tóng）”：Refer to be gathered materials cementing integral engineered composite material by binder materials
General designation.The word of concrete one generally said refers to make binder materials with cement, and sand, masonry gather materials；With water（Additive and admixture can be contained）Coordinate by a certain percentage, it is agitated obtained by cement concrete, also referred to as normal concrete, it is widely used in civil engineering.
In north cold area and salinization of soil area, because of bad environments, the freeze injury of concrete structure is destroyed, and can be produced and be split
Seam and peeling etc., the erosion of salinization of soil is also more serious in addition, so as to can cause the seepage of concrete works, cracking etc., reduces
Its durability and security.And normal concrete obtains that strength grade is relatively low, frost resistance and corrosion resistance are poor, thus need one kind badly
The freeze proof and strong concrete of corrosion resistance.
On the one hand, " water " is Source of life, is the foundation of human survival, but nowadays shortage of water resources and water environment pollution have become the global problem for threatening human development.In recent years, with the fast development of China's economy, the serious mistake of underground water is adopted, and the phenomenon of earth subsidence occur in some areas.Meanwhile, Development of China's Urbanization is accelerated, and increasing waterproof hard surfacing has blocked rainwater backflow, and underground water cannot effectively be fed, and exacerbated the crisis of water resource, even resulted in adverse weather, destroys the balance of ecology.
On the other hand, the regenerated resources utilization of building castoff can make construction industry realize sustainable development, and this is also to build recycling economy and an important component of component conservation-minded society.In recent years, with the fast development of China's economy, Development of China's Urbanization is accelerated, and the demand of natural aggregate increasingly increases, and at the same time, the discharge capacity of building castoff is also increasing, causes serious environment and social concern.One of how the contradiction between both is balanced, the problem of be people's current urgent need to resolve.
In recent years, as economic is greatly developed, China produces substantial amounts of industrial residue because metallurgical every year, wherein, all kinds of non-ferrous metal slags produced during smelting non-ferrous metal, such as copper ashes, titanium slag, manganese slag, lithium slag, nickel slag.Nickel slag is a kind of industrial solid waste residue discharged during smelting ferronickel alloy, dilval is mainly used as producing stainless steel, thus nickel slag is also referred to as stainless steel slag or ferronickel slag, and its chemical composition has larger difference because of the source of ore and the difference of smelting process.China is annual because of production metallic nickel, and generate substantial amounts of nickel slag, it is underutilized for a long time, the stackings of these waste residues not only land occupation but also produces serious pollution to surrounding environment, thus effective processing of waste residue and using just turning into a very urgent problems.
Accordingly, it would be desirable to a kind of new concrete.
The content of the invention
It is an object of the invention to provide a kind of concrete containing quartz sand, the concrete has 20MPa or so compression strength, the coefficient of permeability of 15% ~ 25% effective drainage porosity and 3mm/s or so；Good performance indications, which ensure that, is widely used in the underloading trackbed inspection such as similar pavement, shopping mall and parking lot；Recycle discarded concrete so that economic development and ecological environmental protection tend to be unified, realize the target of sustainable development；Present invention saves natural resources, ecological environment is protected, with good economic benefits and social effect.
The purpose of the present invention is achieved through the following technical solutions, a kind of concrete containing quartz sand, includes each component of following parts by weight：60-65 parts of cement, 2-8 parts of water, 4-5 parts of diatom powder, 2-6 parts of superfine quartz sand, hydrophilic colloid 3-5%, 1-3 parts of lauryl sodium sulfate, 10-15 parts of natural sand.
It is preferred that, the concrete containing quartz sand includes each component of following parts by weight：60.5-64.5 parts of cement, 2.5-6.8 parts of water, 4.2-4.8 parts of diatom powder, 2.4-5.6 parts of superfine quartz sand, 3-5 parts of hydrophilic colloid, 1.3-2.8 parts of lauryl sodium sulfate, 10.7-14.5 parts of natural sand.
It is preferred that, the concrete containing quartz sand includes each component of following parts by weight：61.3-64.0 parts of cement, 3.2-6.4 parts of water, 4.3-4.7 parts of diatom powder, 2.8-5.0 parts of superfine quartz sand, 3.2-4.5 parts of hydrophilic colloid, 1.6-2.4 parts of lauryl sodium sulfate, 11.4-14.0 parts of natural sand.
It is preferred that, the concrete containing quartz sand includes each component of following parts by weight：62.1-63.5 parts of cement, 3.8-6.0 parts of water, 4.4-4.6 parts of diatom powder, 3.0-4.5 parts of superfine quartz sand, 3.5-4.2 parts of hydrophilic colloid, 1.8-2.2 parts of lauryl sodium sulfate, 12.2-13.6 parts of natural sand.
It is preferred that, the concrete containing quartz sand includes each component of following parts by weight：62.7-63.0 parts of cement, 4.5-5.5 parts of water, 4.5-4.6 parts of diatom powder, 3.5-4.1 parts of superfine quartz sand, 3.8-4.0 parts of hydrophilic colloid, 1.9-2.0 parts of lauryl sodium sulfate, 12.8-13.2 parts of natural sand.
Compared with prior art, the invention has the advantages that：
First, research shows, superfine quartz sand has certain activity, superfine quartz sand is finely ground to powder equivalent and replaces cement, used as the mineral admixture of concrete, cement consumption can be not only reduced, it is cost-effective, and also this is respectively provided with very great meaning for saving manufacture of cement raw material, mitigating environmental pollution.In addition, superfine quartz sand is directly sieved into middle sand for building without levigate, natural sand is replaced as fine aggregate part, natural sand consumption can be saved, cost can be equally reduced, good economic benefit is created, also to solve the problem of natural sand is increasingly deficient, new technological approaches is found.
Second, when superfine quartz sand is as cement concrete mineral admixture and as concrete fine aggregate, so as to save cement and sand consumption, regenerated resources are reduced to waste and energy resource consumption, reduce the production cost of concrete, create good economic benefit, therefore the concrete is the features such as have green, environmental protection, energy-conservation.
3rd, because the specific surface area of quartz sand is bigger than the specific surface area of cement, the hole of filling concrete and its hydrated product, inside concrete hole is reduced, so that concrete is more closely knit, and then the endurance quality of concrete is improved, nickel slag can be effectively utilized, is economized on resources.
