Disclosed is building energy-saving hidden honeycomb latent heat concrete with high intensity, excellent fireproofing, waterproofing and anti-cracking performances and good lasting quality, and double thermal properties of heat insulation and heat storage, the processing to a thermal bridge position is convenient, a crack-resistant reinforced layer is not needed, and tapestry bricks can be affixed or paint can be brushed on a working face directly. The invention reduces construction processes and the operational difficulty, increases the construction speed and lowers the labor intensity, and can adjust the temperature intelligently, reduce the indoor temperature fluctuation of the building, improve the comfort level of the indoor environment, and reduce the power consumption. The concrete can be made into insulation blocks used for self-insulation building systems, and can have the same duration as the building.

Description

Hidden honeycomb latent heat concrete
Affiliated technical field
The present invention relates to a kind of building energy conservation thermal technology light weight concrete.The present invention especially relates to a kind of hidden honeycomb latent heat concrete with the preparation of non-crystalline type honeycomb structure porcelain grain.
Background technology
Building energy conservation is a fundamental state policy of China.Use heat preservation technology and improve the important technique measure that the building envelope thermal resistance is a building energy conservation.Present known thermal technology's concrete is generally cement, sand, cinder, perlite, water etc. and mixes, or is mixed and made into foamed concrete with whipping agent and grout.This class concrete has only individual event thermal resistance and thermal resistance value uncertainty height, and thermal capacitance is little, and opposing temperature fluctuation ability is little, and thermal property is relatively poor.The construction operability is relatively poor, and water regain is bigger, easily causes the cracking seepage problem.Because all kinds of thermal technology's concrete crushing strengths are lower, and linear shrinkage is bigger, need do enhancement Layer when cutting off the heat bridge practical application simultaneously, need to use fiberglass gridding cloth in the enhancement Layer, glass fibre can pursue near the corrosion because of learning reaction with cement generation alkalization again; When pasting ceramic veneer, also need make the Clad Steel silk screen in the enhancement Layer and add the nail anchor nails, working procedure is many, complicated operation, and labour intensity is big, and is long in time limit, and each composition material consistency is poor, difficult quality control.
Summary of the invention
In order to overcome the deficiency of existing thermal insulation concrete performance and technical system thereof, the invention provides a kind of hidden honeycomb latent heat concrete, it is little that this hidden honeycomb latent heat concrete not only has shrinking percentage, the specific tenacity height, latent heat is big, but the Intelligentized regulating and controlling temperature has heat insulation and the dual thermal property of energy storage.This hidden honeycomb latent heat concrete does not need to do in addition enhancement Layer in cast after (whitewashing), can be directly bonding applique surface brick or swabbing in its surface, and working procedure is few, and is simple and convenient as the powder portland cement concrete, but suitability for industrialized production becomes insulation blocks.
The technical solution adopted for the present invention to solve the technical problems is: adopt a kind of non-crystalline type honeycomb structure porcelain grain (hereinafter to be referred as NC porcelain grain) to make adiabatic aglite, when proportioning is suitable, NC porcelain grain forms the honeycomb hole that is evenly distributed of relative fixed number at inside concrete, play skeleton and heat insulating function, make gelling material with Portland cement, mineral composition fiber, chrysotile, the PVA fiber, the anticracking material of the compound do opposing of lignin fibre ductility crack, add the brilliant accumulation of heat micro mist of carbon and strengthen concrete thermal storage and energy accumulation performance, and with hydrophobe reinforcement barrier performance, and add an amount of sepiolite, diatomite further improves concrete physicochemical property.
The principal element that influences thermal technology's concrete performance is the performance of adiabatic light granules; the NC porcelain grain that the present invention adopts has the cellular microtexture of ant; crystal grain also has the active hydrogen calcium oxide effect that produces with hydrated cementitious and generates a certain amount of Calucium Silicate powder hydrated adhesive; strengthen structural capacity; stop the moisture content infiltration, the ant polynuclear plane makes crystal grain have flexibility again, absorbs the stress stability volume; reduce shrink grading, prevent the infringement of be full of cracks and frost heave.
The mix Design technology is told us, and starting material are constant, and the grating of sand, stone aggregate well can improve the intensity and the performance such as impervious of cement stone.According to this principle, the present invention's routine of not considering the heat-insulating granules grating of giving up is mixed mode, porcelain grain with different size carries out continuous grading or the mixing of interval grating by predetermined scheme earlier, form good grating, will evenly be full of the space by the porcelain grain of different-grain diameter in concrete structure inside like this, reduce porosity, improved concrete strength and waterproof ability.
Simultaneously and since in the concrete structure uniform distribution the brilliant accumulation of heat micro mist of carbon, when the surface of wall envrionment temperature reaches the micro mist temperature of fusion, micro mist liquefaction, concrete absorbs and also stores a large amount of latent heat; After the surface of wall envrionment temperature dropped to a certain degree, micro mist progressively solidified, and the heat that concrete stores is dispersed in the environment again and goes, and has prolonged the constant indoor temperature time.Make concrete not only keep original thermal resistance function, also had the Intelligentized regulating and controlling temperature function, increased substantially concrete thermal property.Can effectively reduce the buildings fluctuations in indoor temperature like this, healthy comfortable indoor environment is provided, reduce the apparatus of air conditioning number of starts and working time, reduce power consumption, can utilize valley power, peak load shifting, minimizing energy expenditure again.
Accumulation of heat concrete formulation table (mass ratio):
Portland cement 30~60%, NC porcelain grain 40~55%, hydrophobe 0.1~5%, the brilliant accumulation of heat micro mist 5~20% of carbon, mineral composition fiber, chrysotile 0.1~0.4%, PVA fiber 0.1~0.3%, lignin fibre 0.1~0.5%, sepiolite, diatomite 0~20%.

The invention has the beneficial effects as follows, thermal technology's concrete specific tenacity height, linear shrinkage is little, fire-proof and water-proof anticracking and excellent in durability have the dual thermal property of thermal resistance and accumulation of heat, both can make the self-heat conserving structured material, can make heat bridge dedicated processes material again, construction surface need not done the cracking resistance enhancement Layer, directly bonding applique surface brick or swabbing, more convenient processing to heat bridge parts such as windowsill, balcony, air-conditioning shelves.Reduced working procedure, reduced operation easier, improved speed of application, reduced labour intensity, all embodied remarkable advantages at aspects such as convenient construction, reduction of erection time, reduction engineering comprehensive cost, the progress of promotion power-saving technology.The Intelligentized regulating and controlling temperature reduces the buildings fluctuations in indoor temperature, has improved the comfort level of indoor environment, has reduced power consumption.Do not contain inflammable easy aged organic materialss such as rubber powder in the formula materials, improved concrete fireproof and endurance quality, can with the building the same life-span, reduced existing lagging material maintenance update to the pollution of environment and again production power consumption.
