Performance and Implementation of Low-Quality Recycled Concrete Aggregate
Our project seeks to greatly reduce the energy required for concrete production by using mostly recycled concrete. The use of recycled concrete aggregate (RCA) is not a new phenomenon, but has not been studied in the context of low-cost disaster reconstruction efforts, which was our focus—specifically, the 2010 earthquake in Haiti. In our experiments, we sought to replicate the variability in c...
متن کاملDevelopment of Recycled-Modified Asphalt Using Basalt Aggregate
With the strengthened regulation on the mandatory use of recycled aggregate, development of construction materials using recycled aggregate has recently increased. This study aimed to secure the performance of asphalt concrete mixture by developing recycled-modified asphalt using recycled basalt aggregate from the Jeju area. The strength of the basalt aggregate from the Jeju area used in this s...
متن کاملeffect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولReactivity in Recycled Concrete Aggregate
Full scale tests with crushed concrete used in sub-bases in roads show that the material has capacity to reharden, very slowly but also after prolonged periods of time. The rehardening process in crushed concrete aggregate has been analysed with a thermogravimetric method, comparing the change in chemical composition in the aggregate when set with water, compacted and hardened. It has been show...
متن کاملAssessing relationships among properties of demolished concrete, recycled aggregate and recycled aggregate concrete using regression analysis.
Recycled demolished concrete (DC) as recycled aggregate (RA) and recycled aggregate concrete (RAC) is generally suitable for most construction applications. Low-grade applications, including sub-base and roadwork, have been implemented in many countries; however, higher-grade activities are rarely considered. This paper examines relationships among DC characteristics, properties of their RA and...
