Physical and Mechanical Properties of Synthetic Brick From Cement Mortar, Recycled Polyvinyl Chloride and Glass Fiber
In this study, an attempt is made to use glass fiber and recycled polyvinyl chloride (PVC) for making a synthetic
brick, so that we could minimize the extraction of natural resources like sand and lime for making concrete brick. A
synthetic brick was produced by varying the glass fiber composition, as sand substitute in the mixture, and recycled
polyvinyl chloride, relative to cement and recycled PVC weight, was used as binder substitute. After 28 days of curing,
synthetic brick was tested in terms of compressive strength and water absorption capacity. Compressive test showed that the
brick can be used in more impacted area considering that it could be used as a substitute to the commercially available brick.
A decreasing trend of its compressive strength is also observed as the amount of glass fiber increases in the total aggregate
weight. Water absorption test revealed that the produced synthetic brick is more efficient in minimizing water absorption.
This study demonstrated that synthetic brick can be made using glass fiber and recycled polyvinyl chloride as substitute for
aggregate and binder, with huge implication in brick concrete making and also in construction industry.
