Stand -alone net zero energy container houses as temporary offsite working/living
This paper is aimed to investigate and briefly analyze the conditions in Kazakhstan to
predict the effectiveness of operation of standalone net zero energy container house. The description of
Kazakhstani weather conditions as well as container house's characteristics is provided. The comparison
was done between the specifications of solar, wind energy transformation technologies with the data
collected in all regions of the country to check the feasibility of the project. Additionally, the brief
description of stand-alone net zero energy container houses, including both interior-exterior design and
energy control system, are provided
The use of stability index for failure prediction of normally consolidated clays
The new concept of the stability management of soft ground is developed from the laboratory test. The field condition is assumed to be the same as the condition of the CU test because the staged construction is usually used in the field. The stability index (SI) using the stress path is introduced and its application is evaluated in the laboratory tests
Characterisation of cilicate-grouted sand according to dynamic properties at low stress level
Overall, it was found that at lower frequencies, the energy dissipation potential of silicate-grouted sandy soil is higher than that of higher frequencies. Due to validity of approximation that viscoelastic nature of the soil material is linear, the stress-strain relationship of results in an elliptical hysteresis loop. It was concluded that the overall time dependent pattern of creep effect was similar to that of the experiments conducted under constant applied load. By analyzing the creep test results at given frequencies, it was found that while there is an increase in the complex modulus, the complex compliance
and the phase angle decrease. Also, by knowing dynamic properties of soil material, the power law of the creep compliance can be predicted

Development of new sustainable construction materials using by-product sulfur and other industrial by-products in Kazakhstan
The objectives of this project are: 1) to develop new sustainable construction materials using the by-product sulfur and other industrial by-products with special emphasis on long term production of the modified sulfur concrete; and 2) to investigate its potential for use in concrete with satisfying both fresh and hardened properties and providing satisfactory durability performance with respect to deterioration mode of sulfur concrete structure exposed to Kazakhstan’s severe environmental condition such as the combination of freezethaw (F–T) and chloride ion diffusion conditions
