The results indicate that the shrinkage strain of ECC increases with the raising of water-binder ratio, and decreases with the increasing of sand-binder ratio, fly ash content, expansive agent, and shrinkage-reducing agent; The anti-cracking performance is significantly improved along the fiber volume content changes, but it has little effect on ECC shrinkage strain.
Initially, with increasing amounts of sand, the compressive and tensile strengths increase.
With the increasing thickness of sand in rock layer, the critical temperature difference between the sand-free layer increases, and the Ra number decreases, and the natural convection intensity weakens gradually.
For gaseous emissions, carbon monoxide concentrations decreased apparently with increasing ratio of sand bed height/diameter in the second-stage reactor.
A translocation of Aporrectodea longa assessed the ability of this species to live in soils with a high sand content and laboratory work examined growth, maturation and survival of this species in soils with increasing proportions of sand (0 100%).
In our simulation, the following types of bed appeared (in order of increasing amount of sand): sheet flows, sand patches, isolated (barchan) ripples, and continuous ripples.
In general, the physical structure of the bottom consisted of consolidated limestone with gradually increasing amounts of sand (especially in LSB) and rubble towards the central area of the bank (LSB, LHB).
When comparing the model of the present study and that of Kanai et al. (2005), we note that the stage of increasing sand flux (average sand thickness of less than 0.6; sheet flows occur; Fig. 5) corresponds to the free-flow phase of traffic flows.
Increasing the proportion of sand increased the abrasion rate only moderately, while the tendency for charcoal to break down did not vary notably between charring temperatures of 450°C, 600°C, and 800°C, but was notably reduced at 250°C.
Curing time has important role on increasing of compressive strength of treated silty sand soil with lime and pozzolan.
The simulation results show that with the increase of flow rate the maximum erosion rate firstly decreases and then increases, and the maximum erosion rate increases quickly with the increase of sand total flow rate.
