Abstract
The present invention discloses a preparation method of permeable brick by using phosphorous slag, which uses 50 to 150 parts of cement, 15 to 30 parts of water, 140 to 200 parts of bonded silica sand and 140 to 200 parts of phosphorous slag as raw materials, the permeable brick is prepared by the process of vibration, pressure forming and normal temperature curing or steam curing as that of conventional cement brick. The cement is ordinary portland cement with the strength higher than P.O 32.5, portland cement with the strength higher than P.I 32.5 or composite slag cement with the strength higher than P.C 32.5. The partical size of the bonded silica sand is controlled to be between 2.5 mm to 7 mm, the partical size of the phosphorous slag is controlled to be between 0.6 mm to 2 mm. Normal temperature curing is used at the temperature between 5 to 45 DEG C for 1 to 28 days, or steam curing is used at the temperature between 60 t0 120 DEG C for 1 to 2 days. The performance index of the permeable brick prepared by the method meets the requirement in <permeable brick> JC/T945-2005. The permeable brick has good water permeability, mechanical property and abrasive resistance, is applicable in building field widely and reduces the waste and pollution caused by phosphorous slag.
Description
Technical field
The present invention relates to block building element, also relate to concrete, in particular to utilizing yellow phosphorus electric furnace to burn the concrete brick that slag (abbreviation phosphorus slag) is produced.
Background technology
At present the permeable brick used of road mainly contains two types of pottery and coagulation soil properties, and the permeable brick of pottery has advantages such as intensity height, wearability are good, but shortcoming such as these goods need high temperature sintering, have the energy consumption height, and coefficient of permeability is lower.Advantages such as concrete road pavement brick adopts unburned technology, and it is lower to have energy consumption, and coefficient of permeability is better.The patent of building material products such as at present existing pervious concrete road pavement brick is as CN2871620 number " permeable concrete pavior brick ", CN2732807 number " a kind of permeable concrete pavior brick ", CN1651679 number " environment friendly pervious brick structure and method for making thereof ", CN200910136508 number " a kind of concrete permeable brick ", CN101007723 number " a kind of concrete permeable brick that utilizes steel slag as aggregate ", CN1762888 number " high-strength water-permeable concrete floor brick and production method thereof " etc.But, deficiency such as adopt the concrete road pavement brick of above patented method preparation to have secondary material distributing, construction technology complexity, to wear no resistance.Therefore, people's construction material of development of new constantly still.Phosphorus slag is the water collection slag of yellow phosphorus electric furnace, the solid waste of yellow phosphorus factory discharging, and its stacking pollutes the environment.
Still there is not at present the patent application of utilizing phosphorus slag to produce permeable brick.
Summary of the invention
The object of the invention is to provide a kind of method of utilizing phosphorus slag to produce permeable brick, be intended to solve the permeable brick of existing ceramic-like, secondary material distributing and produce concrete permeable brick and exist cost height, power consumption high, and the water penetration of the permeable brick of cement and compression strength such as can not take into account at problem.
Phosphorus slag not only has higher hydration and hardening activity, but also has a large amount of noncrystalline compositions, and wearability is good.The inventor is that raw material is produced permeable brick with the phosphorus slag, and after through repetition test research, the invention technical scheme that provides is with 50～150 parts of cement; 15～30 parts of water; 140～200 parts of mountain sand; 140～200 parts of phosphorus slags adopt the used vibration of conventional cement brick, extrusion forming, and normal temperature or steam-cured technology are made.
Aforesaid a kind of method of utilizing phosphorus slag to produce permeable brick, its optimized technical scheme are with 80～100 parts of cement; 20～24 parts of water; 160～180 parts of mountain sand; 160～180 parts of phosphorus slags adopt the used vibration of conventional cement brick, extrusion forming, and normal temperature or steam-cured technology are made.
Aforesaid a kind of method of utilizing phosphorus slag to produce permeable brick, its described cement are meant Portland cement intensity P.032.5 more than the grade, portland cement intensity more than the P.I32.5 grade or the complex ore slag strength of cement more than the P.C32.5 grade.
Aforesaid a kind of method of utilizing phosphorus slag to produce permeable brick, the particle diameter of its described mountain sand is 2.5mm～7mm.
Aforesaid a kind of method of utilizing phosphorus slag to produce permeable brick, its described phosphorus slag particle diameter is 0.6mm～2mm.
Aforesaid a kind of method of utilizing phosphorus slag to produce permeable brick, its described maintenance method is the normal temperature maintenance, process conditions are: temperature is controlled at 5 ℃～45 ℃, time is controlled at 1～28d, or steam curing, process conditions are: temperature is controlled at 60 ℃～120 ℃, and the time is controlled at 1～2d.
The permeable brick product that the inventive method is produced, performance indications such as its intensity, infiltration coefficient all satisfy JC/T 945-2005 " permeable brick " requirement, and product is the water penetration excellence not only, and compression strength is very high, can use widely at building field; This method has been alleviated the wasting of resources and environmental pollution problems that yellow phosphorus electric furnace burning slag causes simultaneously; Also have the following advantages: prescription and technology path are simple, and production cost is low; With the phosphorus slag particle is aggregate, has good wearability and water penetration.
