Abstract
The present invention provides a kind of for building the green cement sill of 3D printing, is mixed in a certain ratio, is stirred to get by sulphate aluminium cement, mineral admixture, gypsum, reclaimed sand, thickener, retarder, water-reducing agent, water etc..The technology that the invention provides consumes building castoff and industrial by-products in large quantities, reduces production cost, and is made and has excellent performance, meets the cement-based material of building 3D printing demand.
Description
Technical field
The present invention relates to new manufacture fields, while being related to solid waste resource recovery and utilizing field, and in particular to
It is prepared using building waste a kind of for building the green construction material of 3D printing.
Background technique
Currently, Urbanization in China is accelerated, enter on the take-off line of Urbanization.With the expansion of city size
The requirement of big and new era appearance of city, the removal of large amount of building has been inevitable, to bring a large amount of building waste, is given up
Abandoning concrete is exactly one of them.For discarded concrete, current recycling is extremely limited, and most important processing means
It is landfill and stacking.Land resource increasingly in short supply has not only been occupied in the accumulation of a large amount of building wastes, but also seriously endangers periphery
Environment, bring huge pressure to social development and National Environmental Protection Agency.It is well known that the production of construction material is in the useless side of benefit
There are huge potentiality in face, can largely consume waste, turn waste into wealth.Therefore, building waste is re-used for construction material
Production have huge potentiality.
In recent years, 3D printing technique is developed and applies in multiple fields, and 3D printing building will also become construction industry
New production model.3D printing building obviously be unable to do without " ink ", i.e. construction material, and proposes to the performance of construction material
Higher requirement, such as condensation setting rate is fast, cohesiveness is strong.Sulphate aluminium cement has fast solidifying as a kind of special cement
Early strong feature, is able to satisfy the requirement of 3D printing, but its popularization and application are limited because price is higher.
The present invention is the production cost for reducing 3D printing construction material, substitutes a part of water using mineral admixture first
Mud, furthermore using reclaimed sand substitution natural sand or Machine-made Sand, manufacturing cost is not only reduced, and largely consume waste,
With good economic efficiency and social benefit.
Summary of the invention
The purpose of the present invention is to provide a kind of for building the green cement sill of 3D printing, reduces production cost,
Building waste is consumed in large quantities, meets the needs of market is to 3D printing construction material.
In order to solve the above technical problems, technical scheme is as follows:
It is a kind of for building the green cement sill of 3D printing, it is composed of the following components according to mass percent:
Sulphate aluminium cement 20 ~ 40%,
Mineral admixture 0 ~ 20%,
Gypsum 0 ~ 10%,
Reclaimed sand 20 ~ 50%,
Thickener 0 ~ 2%,
Retarder 0 ~ 0.2%,
Water-reducing agent 0 ~ 2%,
Water 9 ~ 20%.
The cement is sulphate aluminium cement, has the characteristics that the energy conservations, emission reduction such as firing temperature is low, carbon emission amount is small.
The mineral admixture refers to that slag, flyash, silicon ash, metakaolin etc. have pozzolanic activity or potential hydraulic
The complementary cementitious material of property.
The gypsum refer to the natural gypsum, desulfurized gypsum, ardealite or other industry by-product gypsums or its dewatered half
Water gypsum.
The reclaimed sand be it is broken by building waste discarded concrete, screening obtains, maximum particle diameter is no more than 5mm.
The thickener is the additive with thickening function such as methylcellulose, carboxymethyl cellulose or cellulose ether.
The retarder, which refers to, extends cement, the additive of gypsum setting time.
The water-reducing agent refers to polycarboxylic acids, how the additive with diminishing function such as to be.
Preparation method the following steps are included:
(1) each raw material is weighed according to the proportion, and water-reducing agent, retarder is soluble in water, stir evenly, for use；
(2) by cement, mineral admixture, gypsum, reclaimed sand, thickener dry-mixed 1 ~ 2 minute in blender；
(3) water solution mixture in step (1) is poured into dry blend and is again stirring for 2 minutes, can take the dish out of the pot slurry transmission
To 3D printing system for printing building.
Beneficial effects of the present invention are that (1) mixes the industrial by-products such as mineral admixture in large quantities, reduce manufacturing cost, and
Reliable guarantee is provided for the sustainable development of enterprise；(2) building waste is consumed, environmental pollution is reduced, discharges a large amount of soils, benefit
In offspring descendants, there is good environmental benefit and long-range social benefit；(3) turn waste into wealth, produce satisfaction building 3D and beat
The construction material of print.
