Use of PC elements for waste minimization in the Sri Lankan construction industry

Purpose – In the construction industry, it is well known that there is a relatively large volume of material being wasted due to a variety of reasons. The problem of material waste on construction sites is not an isolated issue and is of environmental concern. Therefore, waste minimization has become an important issue in the construction industry. The aim of this research was mainly to identify the pre‐cast contribution to the construction waste minimization in the Sri Lankan construction industry, through a comparison of material waste arising from pre‐cast, ready‐mixed and site‐mixed concrete.Design/methodology/approach – Data were collected from 27 building construction projects and three concrete elements: slabs, beams, and columns, were considered to quantify construction waste. To compare the wastage due to pre‐cast involvement with other types, three categories of building projects were used, including projects using pre‐cast concrete elements, in situ concrete elements – site mix, and in‐ situ co...
