Geopolymer concrete is a new kind of environmentally friendly concrete. It gains early strength in room temperature without water curing, and by heating, strength continues to develop. This study investigates the possibility of using geopolymer concrete based on metakaolin (GPC) as a rigid pavement concrete slab material and as an efficient alternative to conventional Portland cement concrete ...

86 lot applications to low-volume and potentially high-volume applications, the pavement must be resistant to all aspects of cold weather maintenance. Concrete curing is required to maintain sufficient moisture to allow cement hydration and concrete microstructure development (Wang et al. 2006). Also, curing has been shown to impact concrete durability as well as concrete strength (ACI 2000).

The rigid pavements are made of Portland cement concrete either plain, reinforced or pre-stressed concrete. The plain cement concrete slabs are expected to take up about 45kg/cm2 flexural stress. The rigid pavement has a slab action and is capable of transmitting the wheel load stresses through a wider area below.

Ponding is the most common method that is adopted for curing concrete floors, slabs, pavements, etc. In this method, the concrete surface is first covered with a moist wrapper for 24 hours. After that, the covers are then removed and a small amount of clay puddles are constructed around all the area. Then water is filled for final curing. 5.
