Abstract
The invention discloses a thermal insulation mortar for building external walls. The thermal insulation mortar consists of sulfate aluminium cement, papermaking sewage sludge ash, polystyrene granules, glazed hollow beads, cellulose ether, an air-entraining agent, a polycarboxylate superplasticizer, alkali-resistant glass fibers and water, and further discloses a preparation method of the thermal insulation mortar. As paper mill sludge ash replaces part of cement, the compactness and the water resistance are very good, the thermal insulation mortar is stable in physical property, free of cracks, ageing-resistant, long in service life and excellent in thermal insulation performance. Not only is harmless utilization of paper mill sludge ash realized to protect the environment, but also resources are saved, waste is changed into valuable, the consumption of cement is reduced, the cost is lowered, and favorable economic and social benefits are achieved. The preparation method is simple, can be completed according to the conventional technology and is low in production cost.

Slag, flyash, silica flour, glass, rubber and cable waste etc. of milling.
Consumption with expanding economy paper is increasing, and the annual mud producing of paper industry brings to environment
Serious pollution.In Europe, paper pulp and paper industry produce about 8,000,000 tons of paper mill sludges every year.Dehydration paper mill sludge is generally adopted
Realize minimizing with incinerating method, this generates paper mill sludge ash (psa).And the residue after burning also is not suitable at present
Processing method it is easy to cause secondary pollution.In China, when often producing one ton of paper, just have 700 kilograms of water content 30%
Paper mill sludge to 98% produces, and sludge yield is 5 to 10 times of same size sewage treatment plant.These paper mill sludges master at present
If by landfill disposal or being used as discarded object stacking, not only to take a large amount of soils, also can cause soil pollution.Cause
How this, processed and be the key issue that paper-making industry need solve using these mud effectively.Application publication number
