The thrust to find new technology and materials has been greatly increasing due to environmental and technological challenges in the progressive world. Among new standard materials and advanced nano-materials that possess a huge potential and superior thermal, mechanical, optical, and magnetic properties, which have made them excellent and suitable components for mechanical engineering applications. The current review paper deals with recent enhancements and advances in the properties of nano-structured glasses and composites in terms of thermal and mechanical properties. A fabrication method of nano-structured glass has briefly been discussed and the phase change material (PCM) method outlined. The comprehensive review of thermal and optical properties confirms that nano-fabricated glasses show both direct and indirect running of band gaps depending on selective nano-structuring samples. The electrical and magnetic properties also show enhancement in electrical conductivity on nano-structured glasses compared to their standard counterparts. The realistic changes in thermal and mechanical properties of nano-structured glasses and composites are commonly attributed to many micro- and nano-structural distribution features like grain size, shape, pores, other flaws and defects, surface condition, impurity level, stress, duration of temperature effect on the selective samples. Literature reports that nano-structuring materials lead to enhanced phonon boundary scattering which reduces thermal conductivity and energy consumption.

In DHC and saline soils and groundwater conditions, the cement mix quickly loses its mobility and workability. In this regard, it is necessary to plasticize it by introducing various surfactants. However, the surfactant additive used should not slow down the process of hydration and hardening. To ensure salt resistance, it is necessary to increase the density and the strength of concrete. The proposed complex additive was obtained by joint grinding in a ball mill of a soda-sulfate alloy (SSA) and gossypol resin (GR) to a specific surface area of 2800 cm2/g at the rate of 05, -1.5%, and 0.1-0.3%, respectively, of the cement mass. The complex additive was introduced into the mixing water of the cement mix. From the research results obtained, it is seen that with an increase in the content of GR from 0.1 to 0.3%, the normal density decreases by 1.4-4 points, and the setting time (due to the accelerating action of the SSA) decreases at the beginning by 20-50 minutes, and at the end by 60-240 minutes. In 28 days, the control cement gained the strength of 56 MPa, and with a complex addition - 60-68 MPa. The introduction of a complex additive led to an increase in the salt resistance coefficient in the reference cement up to 0.55-0.65, and in the cement with a complex additive up to 0.80-0.86; an increase was observed due to the strength and density of the samples. By increasing the strength, it is possible to save 17-21% of cement.
