“…This is caused by the increase in the fineness of the limestone fine aggregate, as also its specific surface area due to the increase in fines amount and hence more amount of water is required to wet the surface of LFA particles. This result in agreement with a result of published from previous research [17][18][19].…”

This paper used the absolute volume method combined with the experiment to determine the compositions of high performance fine-grained concrete (HPFC) and presented the effect of limestone fine aggregate (LFA) and pozzolan (PU) on the HPFC properties. Test results showed that by increasing the LFA and PU, the workability of the concrete mixture decreased, the maximum slump loss after 90 minutes of mixing was 37.84%, whereas the mechanical properties of HPFC increased. The fine-grained concrete mixture containing 40% PU and LFA completely replaced material for natural sand, the compressive strength of concrete at 28-day increased about 23.87% in comparison to the control mixture. By using the standard NT Build 356, the destruction time of the four specimens tested was of 45, 63, 60 and 61 days, respectively. This result is due to the presence of PU increased the volume of the C-S-H, as well as the density of concrete structure and enhanced the strength of HPFC, thus increased destruction time of specimens used for the assessment of corrosion damage of reinforced in the concrete. The results of the current study support the use of the waste limestone from the quarries as a fine aggregate of green concrete in the future.

“…The properties of mortars and concrete in the fresh state can be influenced markedly by their specific gravity, particle size distribution, shape and surface texture of the aggregates [23]. Benabeda et al [24] investigated the influence of the different type of fine aggregate on concrete properties. The experimental results indicated that the rheological properties and strength improved with mixtures of crushed and river sands but decreased with mixtures of crushed and dune sands, especially for higher dune sand content.…”

“…Chinese National Standard BJG19-65 [3] classifies fineness modulus of sand below 1.5 as superfine. The fineness modulus of desert sand, which ranges between 0.194 and 1.009 [4][5][6][7], was not frequently considered in concrete production due to its low workability.…”

Dynamic Mechanical Behaviors of Desert Sand Concrete (DSC) after Different Temperatures

et al. 2019

In the building domain, the non-renewable resource of sand is widely used to produce concrete and mortar. The sand production has been estimated to be more than 10 billion tons with a total of 1.2 billion tons used in concrete in the last decade, which causes the gradual reduction of available building materials and impacts the environment. Since there are abundant desert sand resources in northwestern China, it would be viable to utilize desert sand as an alternative material for concrete production. In this study, an investigation of dynamic mechanical behaviors of desert sand concrete (DSC) was conducted. Various desert sand replacement ratios (0–100%) were used to replace the equivalent hill sand as fine aggregate. Experimental results showed that strain rate had a strong effect on the dynamic mechanical behaviors of DSC. The compressive strength (at room temperature) and flexural strength (after elevated temperature) increased with desert sand replacement ratio (DSRR) with the optimum replacement ratio of 40%, which was because the increase of DSRR improved the compaction of DSC. However, the effect of the low strength of desert sand was higher than that of the compaction when the DSSR exceeded 40%, so both strength values generally decreased with the increase of DSRR. Moreover, the dynamic constitutive model of DSC at room temperature was established on the basis of a nonlinear visco–elastic constitutive model (ZWT model), which can predict the stress–strain curves of DSC.
