Experimental testing of concrete

The next stage of experimental study on testing prototypes of concrete, polymer concrete, polymer cement fiber concrete and concrete polymers was carried out at the "A.S. Akhmetov Nanoengineering Research Methods Laboratory" as part of the program "BR24992867 - Development of resource-saving technologies for the development and management of water management and processing industry in Kazakhstan, creation of an innovative engineering center." Research and development includes the following tasks of the program's calendar plan:

1) 2.5.1 Investigation of the quality of new building materials, geometric

dimensions and shapes of structures;

2) 2.5.2 Investigation of the structure and physico-mechanical and operational properties of hydraulic polymer concrete;

3) 2.5.3 Development of technological parameters for obtaining polymer concrete.

The tests were conducted by Senior researchers, PhD Atenov Y.I. and Master Shanshabaev N.A. under the guidance of Leading researcher, Doctor of Technical Scienses Bekbasarov I.I.

Pre-manufactured concrete prototypes at the first stages of research were subjected to compression testing in order to establish their strength. The types of control and prototype concrete samples, their names and markings are shown in Table 1. The tests were carried out using a hydraulic press P-125 in accordance with the requirements of GOST 10180-2012 Concretes. Methods for determining strength from control samples. Fragments of the process of testing concrete samples for compression are shown in Fig. 1. The test results are shown in Table 2.
