Reading time: 1 minutePrecast concrete construction system has its own characteristics which influence the layout, span length, construction depth, and stability system to a great extent. For instance, inadequate chair bars and insufficient tying of reinforcement would cause rebar movement which may lead to inadequate concrete cover and reduction in effect depth of the concrete section. This results in the porous surface which makes the concrete permeable resulting in less durable concrete.
