Abstract:
The paper presents a new composite material for radiation shielding properties. This material is based on super-heavy concrete reinforced with basalt fiber, which could be used in biological protection systems for neutron radiation sources. The simulation of the neutron transport in the presented material was performed using the Monte Carlo Serpent code. Two types of heavy concretes were considered in the present paper: 1) with ordinary rubble coarse aggregate and 2) with barite coarse aggregate. For each type of concrete, the basalt fiber with dosage from 1 kg/m3 to 50 kg/m3 was added. The cu

Abstract:
Shielding of a reactor is required for protection of people and environment during normal operation and accidental situations. In the present paper we investigated the shielding parameters viz. mass attenuation coefficients, linear attenuation coefficients, tenth-value layer, effective atomic numbers, kerma relative to air and exposure buildup factors for gamma-ray for ordinary, heavy, and super heavy concretes. Macroscopic effective removal cross-sections for fast neutron had also been calculated. Ordinary concrete is economically suitable for mixture high energy gamma-ray and neutron as it h

The construction project is located in Beijing personnel concentration areas which is the special geographical position. The height of the surface construction is about 80m. And the foundation cushion bottom elevation in the most area of foundation excavation project, the circumference is more than 700m, belongs to super large deep foundation pit. During the excavation process, the scheme of setting heavy curtain pile between two adjacent reinforced concrete slope protection piles could effectively control groundwater variation, prevent the possibility dangerous condition in advance and ensure

Abstract:
In modern conditions, the environmental component of building protective materials is guaranteed by the creation of composites capable of protecting underground and above-ground parts of buildings and structures in flooded areas from the filtration of radiation-contaminated water, industrial wastewater, radon, etc. Therefore, the problem of developing modern, including radiation-protective materials for the construction industry is urgent. Concrete is a good moderator and absorber of fast neutrons and intensively absorbs gamma radiation. Concrete consists of cement, sand and gravel. Cement con

Abstract:
It is necessary to have reliable radiation protection for safe operation of different radiation sources. Radiation shielding properties have been studied for a long time both in our country and abroad. However, there is a strong necessity to develop new composite materials, which will provide protection against radiation and have improved mechanical and economic characteristics.

Abstract:
Channel stabilisation with the lining of bed/ banks using cement-concrete (with/ without steel reinforcement as per the size, depth, and capacity), geomembrane, polymers, canvas, ramped earth, vegetation, gravel/ stone pitching, and brick blast is a common practice worldwide to save the adjacent flood plain areas from bank overflowing, seepage, water logging/ salinity, loss of water in irrigation channels, maintaining required water levels and strengthening of channels to be used as transportation means. A trapezoidal channel of cross-section 165 m2 and a lined perimeter of 42m was proposed to
