Abstract
A building mortar is made of cement, powdered coal ash and sand in ratio of 1:(1-10):(1-10). It features use of powdered coal ash instead of lime and partial sand, resulting in low cost and simple process.
Description
The present invention relates to a kind of flyash that utilizes as material of construction, both can reduce environmental pollution, can save lime and sand again, is a kind of flyash (slag) building mortar specifically.
Traditional building mortar, main raw has cement, lime and sand, in the process of manufacturing lime, consumes energy, take out a large amount of sands from the soil and can destroy the arable land again, and flyash is as the industrial waste of heat power plant's large coal-fired boiler, because a large amount of discharging flyash, severe contamination environment, destroyed the eubiosis, therefore the comprehensive utilization of flyash is a difficult problem of studying for many years.In recent years, also there was the people that flyash is used as building mortar.The main drawback of its existence is exactly the processing that the flyash process is complicated, and perhaps mix some Additives again and make finished products, because tooling cost is higher, complex process is not high always to the practical efficiency that makes flyash.For example number of patent application is 93112014, name is called disclosed content in " ultralight, high temperature resistant, high-strength cement mortar " patent application, mainly be that refractory cements adds the flyash extract and adds water and mix, owing to be to utilize the flyash extract: be not directly to utilize flyash, to cost, complete processing all has higher requirements, and utilization ratio is low, the difficult popularization.
Main purpose of the present invention is to overcome the shortcoming in the above-mentioned technology, a kind of flyash (slag) building mortar is proposed,, make full use of the intrinsic characteristic of flyash, to flyash (slag) without any processing, processing, directly mix, make flyash (slag) building mortar, be used for producing with other materials, can use flyash (slag) in a large number, accomplish the waste material utilization, reduced the pollution of flyash, save a large amount of lime and sand again environment.
The object of the invention is realized by following technical scheme: this flyash (slag) building mortar, and to mix stirring by flyash (slag), cement, sand, water and make, the weight ratio of each moiety is as follows:
Title weight ratio (umber)
Cement 1
Flyash (slag) 1～10
Sand 1～10
Water is an amount of, and it is good to be blended into workability
Flyash among the present invention (slag) is by the requirement of GB GB1596-91III grade standard regulation, fineness, water content there is not other requirement, require loss on ignition less than 15%, sulfur trioxide content is less than 3%, and cement, sand are with ordinary mortar used cement and sand.Cement can be with 425
#, or 325
#Or 525
#All can, meet GB GB175-77 and GB1344-77, sand meets the standard of GB GB203-83, water selects for use the clean water that does not contain harmful impurity to stir, general tap water gets final product.
Can determine the different content of cement, flyash (slag), sand in this flyash (slag) building mortar according to purposes.For example be used as when smearing wall face, can suitably reduce flyash (slag) consumption.When flyash (slag) and sand content are higher, promptly when cement: flyash (slag): when the ratio of sand is 1: 7～10: 7～10, can when stirring, add lime putty in right amount, be generally 0.3～0.8 part and get final product, can increase the workability of this flyash (slag) building mortar.
The advantage of this flyash (slag) building mortar is owing to adopt flyash (slag) replacing lime and part sand, the consumption of flyash (slag) is very big, solved the large coal-fired boiler industrial waste: the discharging of flyash, the problem that should occupy that a large amount of places are deposited and environment is polluted, because the characteristics of flyash itself, when preparation flyash (slag) building mortar, reduced cement consumption relatively, improved the mortar workability simultaneously, saved lime, and can reduce by 50% sand using amount, both saved the energy (lime calcining is wanted consumes energy), joint soil can not destroy the soil because of digging sand, 50% of mortar cost can be reduced, construction costs 5% can be reduced with regard to the area, Qingdao.Constructional method is simple, and is easy to utilize.
