aThe effects of the proportion of fine aggregate, the maximum size of the aggregate and the proportion of the 9.5 mm to 4.75 mm particle in the coarse aggregate on the properties of the porous concrete are investigated 比例细颗粒聚合体,最大大小的聚集体和9.5毫米到4.75毫米微粒的比例的作用在粗糙...
Test results indicate significant improvement in the strength properties of plain concrete by the inclusion of up to 80% Copper slag as replacement of fine aggregate (sand), and can be effectively used in structura Also as percentage of Copper Slag increased the density of concrete increased. ...

Compressive strength and flexural strength were determined at age of 3, 7 and 28days. Experimental results indicate an improvement in fresh rheological without reducing in mechanical properties of self-compacting mortars when fine aggregates were replaced partially with DS (50%). However, at high-...
In order to find out the influence of geometric characteristics, distribution and combination condition of mineral aggregates on mixture properties, the si... T Li - 《Advanced Materials Research》 被引量: 1发表: 2012年 The Influence of Fine Aggregate on the Bituminous Mixture Mechanical Behaviour...
A study on properties, static and dynamic elastic modulus of recycled concrete under the influence of modified fly ash ? 2022 Elsevier LtdThe effects of modified fly ash (MFA) on the replacement rate of cement, the quality and replacement rate of recycled fine aggregates (R... H Lin,S Liu...
Finally, an interlinking method of drill cuttings analysis is applied as a tool for estimation of rock aggregates' quality and usability.The studies of mica confirmed the enrichment of free mica particles in fine fractions of the crushed rock compared with initial mica content in the rock. The ...
Concrete properties are usually worsened by the use of high percentages of recycled aggregates of concrete. This paper addresses the efficiency of using recycled concrete as an aggregate by systematically presenting results on the influence of silica fume on recycled aggregate concrete (RAC) properties...
Crumb rubber from scrap tires (2–6 mm) were employed by Najim and Hall (2012) as a partial substitute for Fine Aggregate (FA), Coarse Aggregate (CA) and mixed Fine and Coarse Aggregate (FCA) in self compacting concrete at weighted proportions of 5%, 10% and 15%. It has been asserte...
This paper presents the hardened properties of a high-performance fibre-reinforced fine-aggregate concrete extruded through a 9mm diameter nozzle to build layer-by-layer structural components in a printing process. The printing process is a digitally controlled additive method capable of manufacturing arc...
