Abstract: In the process of in situ heat injection mining of coal seams, a circular combustion chamber will gradually be formed. However, for the interlayer coal seam, the interlayer will gradually suspend in the combustion chamber. ...

Abstract: Surface treatment, using two slurries containing nanomaterials, was applied to recycled aggregate (RA). Experimental studies were conducted (1) to compare properties of RA before and after the surface treatment; and (2) to ...

Abstract: In this study, the effect of nano-SiO2 on the mechanical properties, microstructure, and hydration process of cementitious materials incorporating hydrophobic admixture (CM-HA) was studied through mechanical strength and ...

Abstract: Fiber-reinforced calcareous sands manifest unique properties of increased shear strength and particle breakage. These features are of practical importance for some offshore engineering constructions because the strength ...

Abstract: Surface treatment, using two slurries containing nanomaterials, was applied to recycled aggregate (RA). Experimental studies were conducted (1) to compare properties of RA before and after the surface treatment; and ...

Abstract: Heterogeneous constellations are composed of satellites with different structures

Abstract: This article puts forward a computationally efficient block matrix based precise integration algorithm for solving vibration response subjected to time-variable excitation and nonlinearity, especially for nonhomogeneous ...

Abstract: The slow formation of magnesium silicate hydrate (M-S-H) results in insufficient early strength of M-S-H cement, restricting its wide application. In this study, nanosilica (NS) was applied to modify the performance of ...

Abstract: The analysis result of liquid fuel combustion performance shows that the factors affecting chamber combustion are the vaporization and atomization of liquid fuel. At the same time, the combustion chamber conditions and the ...
