Abstract
To improve the undesired characteristics of concrete, for example high CO2 emission and loss of strata from quarrying of raw materials, environmentally hazardous solid waste could be utilized as cement, sand and/or aggregate replacement. Apricot Pip Shells (APSs) are an environmental problem mainly in the region where apricots are cultivated. The shells are burnt as a fuel by local people in this region. An alternative use for this waste material would be for aggregate replacement in concrete as reported in this paper. In this study, limestone aggregate were substituted by different percentage of APS in the prepared concrete mixes. Unit weight, compressive and tensile strength tests were conducted on the specimens. A decrease was observed in the strength development of the concrete containing APS. This may have resulted from the weak adherence between APSs and cement paste in the interfacial transition zone. However, the unit weight of the concrete decreased for higher APS content in the mix.
Highlights
Since increase in cost of the raw materials and the decrease in the natural resources, use of the waste materials in concrete is an effective resource for the construction industry
The test results indicate that it is possible to utilize of Apricot Pip Shells (APSs) in concrete mixtures
− Based on the experimental results, the concrete including APS resulted in lighter weight concrete
Summary
Since increase in cost of the raw materials and the decrease in the natural resources, use of the waste materials in concrete is an effective resource for the construction industry. Limestone aggregate is substituted with the different replacement levels (0%, 5%, 10%, 15%, 20%, 25%, 30%, 35% and 40%) of APS aggregate in the prepared concrete mixes.
