the concrete's internal relative humidity drops to about 80%. However, if moist curing is resumed, strength devel-opment will be reactivated, but the original potential strength may not be achieved. Although it can be done in a laboratory, it is difficult to resaturate concrete in the field. Thus, it is best to moist-cure the concrete continu-

Design of liquid retaining structure is different from ordinary R.C.C, structures as it requires that concrete should not crack and hence tensile stresses in concrete should be within permissible limits. A reinforced concrete member of liquid retaining structure is designed on the usual principles ignoring tensile resistance of concrete in bending.

Check the concrete mix. The strength of concrete determines the load a structure can bear and carry. Usually, developers monitor the quality and strength of the concrete, but at times, it gets difficult to prepare the mix and check the concrete every time. In such cases, it is always better to opt for ready-mix concrete as an alternative.

Precast reinforced concrete frame with cruciform and linear beam elements (Seria 106) is an example of a frame system with precast beam-column subassemblages (Kyrgyzstan, WHE Report 33). The system was developed in Kyrgyzstan in 1975. The load-bearing structure consists of a precast reinforced concrete space frame and precast floor slabs.

The precast concrete is transported to the construction site, lifted and positioned at the predetermined place. The cast-in-situ concrete is a standard concrete which is poured into the specific formwork on the site and cured to get the strength of RCC elements. Here, we will discuss the differences between the precast & cast-in-situ concrete.
