“…Earlier, the [13] determined optimum parameters of the activation of cement suspension in RPD (duration of activation, the share of cement for the activation by the calculated mass). The selection of optimum parameters was specified by obtaining the best physicomechanical properties of cement compositions while power consumption during the work of RPD was considered.…”

“…The selection of optimum parameters was specified by obtaining the best physicomechanical properties of cement compositions while power consumption during the work of RPD was considered. The optimum duration of activation in RPD was 2 min., in this case 50 % of an estimated amount of cement was exposed to activation [13,17].…”

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.

This article has certain goals and tasks for solving some engineering problems. The analysis of the situation regarding the applicability of risk management in the construction industry of the Russian Federation is presented. The reasons for the low prevalence of this means of ensuring the mechanical safety of buildings and structures are revealed. Examples of the application of risk management in the West, as well as examples and reasons for non-use in Russia are given. Measures and recommendations are proposed to change this situation in the construction sector. References are given to sources with weighty arguments for the application of building safety.
