Background technology
Current Chinese architecture is just in the ascendant, and building construction increases year by year, reaches 500,000,000 square metres in 2003, mainly is public building, factory building and dwelling construction, and the ratio maximum that dwelling house accounts for.Shanghai only, 1,600 ten thousand square metres in annual newly-built dwelling house, expection in 2003 surpasses 2,000 ten thousand square metres, and old house is transformed about 200,000,000 square metres.Therefore, the required gelling material enormous amount of building construction, but the gelling material of using on the present engineering remains traditional material, can't improve construction quality.Therefore China's building construction quality still seriously exist splitting of just obviously seeing in appearance, take off, distension, leak, ooze, surface phenomena such as mould, see through this surface phenomena, can cause more serious adverse consequences:
(1) buildings function reduction.With the dwelling house is example, does not reach requirement as thermal and insulating performance, just must reduce the and comfortable for living sense, is difficult to make resident family to be lived in peace; If under this condition, still keep and comfortable for living, temperature, humidity in the just necessary electrical installation surge chamber, this must increase energy expenditure.The present house building enclosure unit surface heat transfer capacity of China is 2～3 times of the close developed country of weather condition, and energy dissipation is quite surprising.
(2) interior of building is impaired, comprises whole the damage and or local damage.This not only is related to the performance of material therefor, and involves the matching problem of material and material, and is improper as materials, must cause with the cohesive force of matrix inadequately, and drum, peeling phenomenon have taken place.
The reconstruction or the repairing that are caused by these two kinds of reasons (buildings function reduction or impaired) must consume the material of construction that this should not consume, directly waste energy and resource, be unfavorable for very much Sustainable development, therefore, should particularly novel building mortar and corresponding new technology be avoided this phenomenon by using novel material.
