Description
Technical field
The present invention relates to a kind of building material field, particularly relate to a kind of additive being exclusively used in mechanically spraying mortar, specifically a kind of densification powder being exclusively used in mechanically spraying mortar.
Background technology
Mechanically spraying mortar construction technology derives from Europe, has successfully used nearly 40 years in Europe. Mechanically spraying plastering technique goes for civil buildings and public building, and can be greatly promoted the work efficiency of wall plastering, shortens the completion cycle. And traditional method manually plastered the causes problems such as efficiency of construction is low, material consumption is surprising, dust from construction sites pollution also have artificial cost increase is always up developer and the problem that contractors are perplexed most, it is that mortar being stirred is pumped into spray gun by pipeline that mechanically spraying is plastered, relend the pressure helping air compressor, mortar is continuously and uniformly sprayed on metope and ceiling, rub with the hands in fact then through levelling, complete floated finish.
Therefore mechanically spraying mortar is a trend of commodity mortar development, the performance of Machine-blasting mortar has much room for improvement in the market, the requirement of mortar mixture is high water retention, low viscosity, good cohesive force and anti-sag performance by machine pressure spray process, but presently commercially available grout additive or densification powder can not well be applied in mechanically spraying mortar.
Summary of the invention
It is an object of the invention to provide a kind of densification powder being exclusively used in mechanically spraying mortar, this densification powder joins in mortar, mortar mixture can be made to have high water retention, low viscosity, good cohesive force and anti-sag performance, and intensity effect is little, meet the performance requirement of mechanically spraying mortar.
For realizing this goal of the invention, the technical solution adopted in the present invention is: a kind of densification powder being exclusively used in mechanically spraying mortar, composed of the following components, and parts by weight are:
