Cement stabilized macadam base is widely used as a road building material in various grades of highways. Based on the law that the base cracking is mainly affected by the shrinkage of cement stabilization materials, this paper introduces the method of adding micro-expanding cement to the base that can effectively reduce the hydration shrinkage coefficient and dryness shrink factor. At the same time, it is pointed out that strict control of the amount of micro-expansion cement and the quality of the construction can also effectively reduce the occurrence of cracks in the base.

This has created a need for sustainable alternatives that maintain concrete’s quality and performance.

Concrete is a mixture of cement, sand, gravel, and water. In order to obtain good quality in the process, added ingredients, waste, or other materials with a certain ratio value are added. In this case, the use of granite waste as a substitute for coarse aggregate that is easy to find and the use of silica fume which aims to increase the compressive strength of concrete. The purpose of this study was to determine the effect of granite waste and silica fume, as well as the relationship between compressive strength and tensile strength of concrete with these variations.

Abstract Over the past 15 years, the diminishing availability of natural sand has prompted the exploration of alternative solutions in the construction industry. This paper investigates the viability of using crushed rocks such as granite, gneiss, dolerite, and basalt to produce artificial sands as substitutes for natural sand. Focusing on the concrete production sector, our research explores the utilization of marble dust (MD) and granite dust (GD) to enhance concrete properties while addressing environmental concerns associated with the scarcity of natural sand.

As the construction sector is growing and with the passage of time, several types of concrete were made globally like high strength concrete, self-healing concrete, self-compacting concrete and self-curing concrete. The global demand for building materials is steadily growing, yet the supply of natural resources is diminishing. Every day extraction of sand that is naturally occurring in river beds is destroying the natural quality of river bed and this process of extraction is damaging the flow properties of river and the seepage of water to the retention of ground water level is decreasing da

Understanding the change of permeability of rocks before and after heating is of great significance for exploitation of hydrocarbon resources and disposal of nuclear waste. The rock permeability under high temperature cannot be measured with most of the existing methods. In this paper, quality, wave velocity, and permeability of granite specimen from Maluanshan tunnel are measured after high temperature processing. Quality and wave velocity of granite decrease and permeability of granite increases with increasing temperature. Using porosity as the medium, a new wave velocity-permeability model

The bonded particle model (BPM) of granite for pre-stressed machining is build by using the discrete element method (DEM). This model can not only descript the intergranular fracture behavior but also the transgranular fracture behavior of the granite. The processes of crack propagation under different pre-stressed machining conditions are studied by means of DEM simulation. Damages and cracks of surface/subsurface are also observed. The simulation results show that, while the magnitude of pre-stress is controlled in a certatin range, the number of radial cracks reduce as the increasing of pre

Such soils exhibit mechanical characteristics such as loose, rich cracks and easy disintegration, resulting in severe soil erosion disasters under rainfall conditions. Microbial-induced carbonate precipitation (MICP) is a green alternative for soil stabilization. In this study, a new strategy for the disintegration control of granite residual soil using MICP technology is proposed.

Abstract A five-axis CNC-VMC machine tool generally has a high-speed spindle spinning at a maximum rotation of 50,000 rpm, under which the machine tool bed will violently vibrate that leads to poor machining precision and surface quality of workpiece. The gray cast iron, as the typical material of a machine tool, exhibits poor dynamic suppression of vibration that its processing yield and quality can no longer satisfy the product demand of current market. Consequently, in this study, we proposed granite composite material (GCM) in place of gray cast iron for the structure of machine tool, whic
