Heat loss from floors on slab can be estimated by equation: Q = F * P * (T i T o) Where: 1) F is the Heat Loss Coefficient for the particular construction in Btu/hr ft°F 2) P is the perimeter of slab in ft 3) T i is the inside temperature in °F 4) T
The water–cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. A lower ratio leads to higher strength and durability, but may make the mix difficult to work with and form. Workability can be resolved with the use of plasticizers or superplasticizers.. Often, the ratio refers to the ratio of water to cementitious materials, w/cm. Cementitious ...
