Description

A kind of fibre cement gravity flowing levelling mortar and preparation method thereof
Technical field
The present invention relates to building material field, in particular to a kind of fibre cement gravity flowing levelling mortar and its preparation side Method.
Background technology
Self-leveling material have good mobility and stability, easy construction, it is bright and clean it is smooth, intensity value is high, leveling layer The advantages that thickness is thin, good water-fast acid resistance, is the industrial grounds such as parking lot, factory floor, large supermarket, warehouse, market Levelling ideal material and a developing direction of building ground construction now, market potential are very big.It can be in injustice It is used in substrate, a smooth, smooth, firm, wear-resisting place mat bottom, such as the essences such as carpet, timber floor, PVC, ceramic tile is provided Alignment material.
Ground cement gravity flowing levelling mortar, with portland cement with quick-drying quick-hardening cement (such as aluminate cement or aluminium sulfate Cement) it is cementitious material, granular aggregat (quartz sand) and fleut (dicalcium powder, mountain flour, active mineral admixture) are added in, And be modified using chemical admixtures such as cellulose ether, water-reducing agent, early strength agent, retarder, redispersable latex powders, for ground The levelling new terrestrial cement-based material in face.In use, plus water, powder adjust by a certain percentage after mixing high fluidity pulpous state, After phenomena such as isolation, bleeding, sedimentation, be poured into ground slightly through pave can automatic levelling, and formed smooth, wear-resisting, resistance to The surface of pressure.
Self-leveling material has fabulous mobility, quick coagulability, makes it that can construct in a short time, and coagulation The bonding of soil matrix bottom is secured, and with strong mechanical performance, good wear resistance.Since cement-based material is compound crisp of multiphase Property material, volume stability be influence its durability an important factor for, the bad generation that can lead to crack of volume stability, influence Its performance, contractile mechanism is more complicated, and influence factor is also more.At present, just different contractile mechanisms, researchers are common Propose 6 types:Chemical shrinkage, plastic shrinkage, dry contraction, self-constriction, temperature drop is shunk and Carbonization contract, and this 6 kinds The hydration and hardening for being contracted in cementitious material influences each other in the process, mutually promotes.For cement self-leveling mortar, gravity flowing levelling mortar Belong to layer material, compared with mass concrete, temperature drop shrinks unobvious;A large amount of uses of high efficiency water reducing agent, glue compare Low, aquation initial stage bleeding is seldom, this results in mortar early-age plastic shrinkage to develop;Since cement consumption is big, and also introduce big The fast hard cementitious material of the larger quick-drying of the heat of hydration is measured, hydration rate is fast, chemical shrinkage caused by aquation, self-constriction and dry receipts Contracting is more notable.
Wind energy is a kind of clean forever continuous energy, and available wind energy is distributed widely in the world.Therefore, wind Power, which generates electricity, is increasingly becoming the important component of many National Sustainable Development Strategies.Glass fibre reinforced composion is than strong Degree, specific modulus are high, and anti-fatigue performance is good, are widely used in manufacture wind electric blade composite structure, but glass fiber reinforced plastics composite material by The enchancement factors such as manufacturing process, use environment influence, and wind electricity blade can inevitably generate the structures such as fibrous fracture, starved and layering and lack It falls into, its service life is caused to decline, leads to waste and old wind electricity blade bulk deposition, cause environmental problem, energy problem, society are asked Topic.According to statistics, 2010~2024 years, China's wind-power electricity generation class composite scrap amount of substance was 10107~12634t (containing production About 10050 tons of waste);197643t is quickly increased to from 18090t within subsequent 5 years, i.e., change in great-jump-forward.
Recycling for the waste and old wind electricity blade of the composite fibre of bulk deposition, its processing mode is-entirety profit at present With, be the key that solve the problems, such as wind electricity blade solid waste largely discharge and accumulation and effective way.At present, whole utilization wind The major domain of electric blade solid waste is building materials field, is processed into construction material (such as mortar, concrete, water Mud etc.) the advantageous ingredient of property development, it is more rare for the report of composite fibre waste and old wind electricity blade improvement gravity flowing levelling mortar.
In view of this, it is special to propose the present invention.
