Abstract
The invention discloses novel mortar for air-entrained bricks. The novel mortar is prepared from the following ingredients (by weight): 60% of quartz sand, 10% of fly ash, 4% of zeolite powder, 2% of meerschaum, 0.5% of hydroxyethyl methyl cellulose, 3% of diatomite, 4% of quicklime, 8% of cement, 2% of aluminium powder, 4.5% of redispersible latex powder, 1% of a water reducer and 1% of an additive. The invention has advantages of simple production process and low cost. The prepared mortar has good strength, low heat conductivity and very good anti-crack effect, is energy-saving and environmentally-friendly, satisfies needs of constructional engineering and meets environmental protection requirements. By adding expansive soil into cement for calcination modification, adhesion of cement in the mortar is enhanced. By adding diatomite obtained after technological modification, performance of the mortar is improved, and the mortar has little shrinkage deformation. By using 1 wt% of cellulose ether as an additive, bondability of the ingredients is raised so as to further enhance strength of an air-entrained brick.
Description
Technical field
The present invention relates to material of construction and make field, particularly relate to a kind of novel aerated bricks mortar.
Background technology
Gas concrete brick because of there is lightweight, heat-insulating property and sound-absorbing effect good and have the plurality of advantages such as some strength, the problems such as existing aerated bricks long-standing construction wall seepage, cracking, intensity are low; Aerated bricks is large with mortar water-intake rate, is difficult to have the over-all properties of good cracking resistance, weather resistance, shock resistance, antidetonation and fire-resistance calamity.
Summary of the invention
The object of this invention is to provide a kind of novel aerated bricks mortar, be achieved through the following technical solutions:
A kind of novel aerated bricks mortar, is made up of following composition: quartz sand 60%, flyash 10%, zeolite powder 4%, sepiolite 2%, hydroxyethylmethyl-cellulose 0.5%, diatomite 3%, unslaked lime 4%, cement 8%, aluminium powder 2%, redispersable latex powder 4.5%, water reducer 1%, additive 1% by weight percentage.
Further, described sepiolite need be crushed to 50-100 order, with hydroxyethylmethyl-cellulose Homogeneous phase mixing, under aerobic conditions, is heated to 75-80 DEG C, continues 0.5-1 hour, is cooled to room temperature.
Further, described unslaked lime and aluminium powder need grind 2-3 hour at 180-200 DEG C of temperature lower calcination.
Further, described redispersable latex powder is acrylate and styrene copolymerized rubber powder.
Further, described water reducer is melamine based water reducer.
Further, described additive is ether of cellulose.
Further, described diatomite is through process modification process: adopted by diatomite the salt acid soak of 1% concentration after 30 minutes, filters, then adopts 5% sodium hydroxide solution to soak, and heats and carry out grinding 30-40 minute, naturally cools to room temperature, filters, dry.
Further, described cement is through calcination processing: the swelling soil adding its weight 1% in cement, mixes, at 300-350 DEG C, carry out calcining 1-1.5 hour.
The invention has the beneficial effects as follows: compared with existing aerated bricks mortar manufacturing technology,
(1) production technique of the present invention is simple, and cost is low, and the mortar strength made is good, thermal conductivity is low, effect of prestressed is very good, energy-conserving and environment-protective, meets the needs of construction work, meets the demand of environmental protection;
(2) the present invention carries out calcining modification by adding swelling soil in cement, and the cementability of cement in mortar is strengthened; By the diatomite that adding technology is modified, improve the performance of mortar, make mortar dry-shrinkage deformed little;
(3) the present invention adopts the ether of cellulose of 1% weight percent to do additive, improves the associativity of each composition, thus improves the intensity of aerated bricks further;
(4) have good water-fast, the problems such as high and low temperature resistance, solves the greatly dry-shrinkage deformed of common general aerated bricks mortar, splitting resistance, frost resistance difference.
Embodiment
A kind of novel aerated bricks mortar, is made up of following composition: quartz sand 60%, flyash 10%, zeolite powder 4%, sepiolite 2%, hydroxyethylmethyl-cellulose 0.5%, diatomite 3%, unslaked lime 4%, cement 8%, aluminium powder 2%, redispersable latex powder 4.5%, water reducer 1%, additive 1% by weight percentage.
Further, described sepiolite need be crushed to 50-100 order, with hydroxyethylmethyl-cellulose Homogeneous phase mixing, under aerobic conditions, is heated to 75-80 DEG C, continues 0.5-1 hour, is cooled to room temperature.
Further, described unslaked lime and aluminium powder need grind 2-3 hour at 180-200 DEG C of temperature lower calcination.
Further, described redispersable latex powder is acrylate and styrene copolymerized rubber powder.
Further, described water reducer is melamine based water reducer.
Further, described additive is ether of cellulose.
Further, described diatomite is through process modification process: adopted by diatomite the salt acid soak of 1% concentration after 30 minutes, filters, then adopts 5% sodium hydroxide solution to soak, and heats and carry out grinding 30-40 minute, naturally cools to room temperature, filters, dry.
Further, described cement is through calcination processing: the swelling soil adding its weight 1% in cement, mixes, at 300-350 DEG C, carry out calcining 1-1.5 hour.
With on strength grade, test comparison is carried out to mortar of the present invention and general aerated bricks mortar:
Table 1
As can be seen from Table 1, mortar of the present invention will improve much than general mortar under same intensity grade in performance.
