Abstract
Nowadays, the construction of cement composite using 3D printers is considered one of the most promising methods of automation of building processes. However, the compositions of cement composites have several disadvantages, such as high cost, short workability and etc. It has been suggested that clay soil as an additive will help to solve these problems partially. The aim of the work is development the cement compositions with clay soil, for use in 3D printers to construction. The composite consists of cement paste with clay soil and additives. To study printability of a composite the rheological properties in a fresh state were studied. The study of the rheological properties of composites was carried out using a flow table test for mortar. The key factor for determining the suitability of the composite for printing was accepted the diameter of the cone after shaking. The test results showed the possibility of replacing cement paste with clay soil up to 25% which leads to a reduction in the cost and an increase in printability with a slight decrease in the strength of the obtained material to 7%. Utilizing of soil from the construction site provides maximum economic efficiency of the material application.
Highlights
The purpose of this work is to obtain a composition for 3D printing with the required stiffness, increased print workailability time and low cost
The experimental works proved the possibility of using clay soil as filler for cement paste for 3D printer
The findings suggest that the clay soil influence the properties of composite material in the effective and positive way
Summary
The purpose of this work is to obtain a composition for 3D printing with the required stiffness, increased print workailability time and low cost. The object of study is cement composites used in 3D printers. The properties of obtained material must requirements for the compositions used in 3D printers for the construction. The raw materials used in the elaboration of compositions are local deposits of clay soils, portland cement and various additives. Clay soil is a cheap and strong material. It is located in large amounts near construction sites and does not require complex preparation for use as additives or as a main ingredient for soil-concrete building materials
