Abstract
The invention relates to a method for compressing civil engineering blocks with mud solidifying material. The method comprises the following steps: firstly, mud adjusting treatment: the mud is evenlymixed so as to remove foreign matters, and the required mixing proportion for mud solidifying is accounted by a sampling test; secondly, matching according to the following weight percentages: high molecular flocculant accounts for 0.5-3.0 percent, the mud accounts for 55-85 percent, and cement or fly ash accounts for 10-45 percent, the high molecular flocculant, the mud and the cement or fly ashare put into an agitator for blending after metering, and the excess moisture is removed; thirdly, the well-prefabricated die is utilized for molding; fourthly, pressure is increased on a vibrating pressurizing platform under the 5-15MPa operating pressure; and finally, after the standard indoor curing is performed, the mud solidifying material is produced to compress the blocks. The method for compressing the civil engineering blocks with mud solidifying material fully utilizes the process that the mud solidifying material is not required to be sintered at the normal temperature for producingthe blocks, the mud solidifying material is changed into valuables, therefore, the resource utilization field of the mud solidifying material is extended, and the problem that the civil engineering materials lack increasingly is eased.
Description
Technical field
Pressing civil engineering block from sludge solidification material is the friendly section bar material of a kind of novel environmental, relates to the manufacture craft of sludge solidification material application approach and the building block of mud system, belongs to the civil engineering material field.
Background technology
For the quality problem in river training lake, guarantee the unimpeded of normal flood carrying capacity in river course and thoroughfare, large-scale dredging and desilting engineering have been carried out in some river courses and lake.In addition, along with coastal economy and seaborne fast development, the construction and the maintenance of harbour, navigation channel, ocean and coastal engineering increase rapidly, also produce a large amount of dredging silts.Though in recent years, Chinese scholar has been carried out many useful explorations and research work in sludge solidification processing and resource reutilization field, and relevant sludge solidification material project application scope is limited.The building block that existing use mud is made need be added a large amount of sandstones and cause cost to improve; Perhaps need to use setting box and mud and the integrally formed formation building block of curing materials, the block strength of making is lower, and construction technology is loaded down with trivial details.In order to improve intensity the method that adopts sintering technology to use mud making clay brick is arranged also, but a large amount of energy of sintering consumption also cause certain harm to environment simultaneously.
Summary of the invention
Technical problem: at the deficiencies in the prior art, the invention provides a kind of cheap be the preparation method of primary raw material, the high-intensity wood building block that does not need sintering with mud.
Technical scheme: purpose of the present invention realizes by following technical scheme:
The method of pressing civil engineering block from sludge solidification material is characterized in that: may further comprise the steps:
A. mud transfers mud to handle: mud is stirred, remove foreign matter (stone, wood chip etc.), by sampling test, calculate the required match ratio of sludge solidification;
B. by following weight percent proportioning: polymer coagulant: 0.5%-3.0%, mud: 55%-85%, cement or flyash: 10%-45% sends into mixer and stirs after the metering, remove excessive moisture;
C. with prefabricated mould molding;
D. operating pressure is that the 5-15MPa vibration adds the upward pressurization of presenting a theatrical performance as the last item on a programme;
E. after the indoor standard curing, make sludge solidification material compacting building block.
By this technical scheme, in the manufacture craft process of building block, (need not through and firing) that curing sludge is made into civil engineering block at normal temperatures, can reduce and produce power consumption.
Beneficial effect: pressing civil engineering block from sludge solidification material makes full use of mud system curing materials, (need not through fire) makes civil engineering block with curing sludge and can reduce and produce power consumption at normal temperatures, thereby reduce cost, and the product strength height that forms.By suitability for industrialized production sludge solidification material is turned waste into wealth, enlarged the recycling field of sludge solidification material, reduced simultaneously and produced the wilderness demand of civil engineering block, thereby alleviate the problem of civil engineering material worsening shortages land resource.
