Valorization of seashell by-products in pervious concrete pavers
Highlights Seashell By-Products (SBP) size highly influences the granular arrangement of matrix. The SBP can effectively replace gravel 2/6mm for pervious concrete pavers. SBP 2/4mm provides a good compromise for the overall composition of the matrix. SBP 4/6.3mm decrease in mechanical strength and promoting the water infiltration. The compaction pressure into a single layer of 7.4kPa is optimal with good strength.
Abstract Seashell By-Products (SBP) are produced in an important quantity in France and are considered as waste. This paper studies their use as a partial replacement of aggregates in pervious concrete pavers considered as an environmentally friendly building material. After designing the control pervious concrete pavers by investigating the energy and the pressure compaction, the coarse aggregate fraction were partially (20% or 40% by mass) replaced by SBP obtained from the Crepidula shell. The crushed Crepidula seashell of 2/4mm and 4/6.3mm were used to make new seashell by-products based pavers. In this paper, the mechanical and hydrologic properties of both pervious concrete pavers were determined. Results show that the seashell by-products have the potential to be used as aggregate. The mix design allows achieving both a compressive strength of 16 and 15MPa for respectively the control pervious concrete pavers and the seashell by-products based pavers and a permeability coefficient in the range of 3–8mms−1.
