The use of recycled concrete aggregates in the application of insulating composite building units within the demolished areas in Syria

Abstract

The Syrian crisis has emptied tons of demolition waste and concrete rubble, which is still an obstacle in the process of reconstruction and slowing its movement, because so far no studies and foundations have been developed for its disposal except in its placement within the road paving works and some cement mixtures allowed according to the experiments carried out by structural researchers, and therefore it was The main objective of the study is how to get rid of concrete rubble effectively in the simplest and least expensive way due to the weak capabilities available in Syria due to the current economic blockade.

The study revolves around the application of composite insulating materials with the same principles of manufacturing insulating composite panels globally, by linking the recycled cement materials with the insulating materials by the method of adhesive, and not by the method of mixtures, which showed their complete ineffectiveness with the recycled cement materials in terms of quality and cost.

The research dealt with an in-depth understanding of the concrete aggregate and the mechanism of extracting it from the site in the simplest ways and according to the available capabilities in Syria, in addition to a detailed explanation of the components of insulating composite materials and the standards for their manufacture.

The research also relied on the inductive analytical method by collecting global models and experiences that relied on implementing their experiments with recycled cement materials extracted from the surrounding or demolished site.

The research found the manufacture of a new product consisting of concrete aggregate with an insulating layer using the insulating composite panels manufacturing system, and tests were conducted on it to ensure its effectiveness and the possibility of its inclusion within the local market in the process of reconstruction of the demolished site.
