Loads are the forces that come on the structure during construction or during service period. It is very necessary to define all the loads that structure is going to support, once the dimensional requirements have been defined. It is so …
Water to cement ratio is ratio between the weight of water and the weight of cement that is used in a fresh concrete mix. Water to cement ratio is one the largest single factor on which strength of compacted concrete …
Vibration of concrete is carried out for the sake of consolidation. The main objective of vibration is to compact the concrete and to achieve the maximum possible density of concrete. Almost 5 to 8% by volume of freshly placed concrete …
Bulk density of aggregates is the mass of aggregates required to fill the container of a unit volume after aggregates are batched based on volume. It depends on the packing of aggregate i.e. Either loosely packed aggregates or well dense …
Specific heat is the heat capacity of a material that it absorbs to raise the temperature by one degree Celsius. In case of concrete, it is the heat capacity of concrete. Specific heat is measured in joules per kg per …
Thermal diffusivity is used for the calculation of thermal conductivity. It represents the rate at which temperature changes within a defined mass. It is represented by δ and it is measured in meter square per hour. Thermal diffusivity is like …
Thermal conductivity is the ability of the material to absorb heat. It can also be defined as the ratio between the heat flux and the temperature gradient. Unit of thermal conductivity is joules per second per square meter. Conductivity of …
In thermal curing heat is applied to the concrete for the purpose of accelerating the gain of early concrete strength. There are several thermal curing methods that can be used, but each method has some specialized properties that make it …
Compressive strength of concrete is affected very prominently by the strength of aggregate, its moisture content, grading, surface texture and the maximum aggregate size. For the making of high strength concrete, aggregates like quartzite, trap rock or felsite are required …
With the passage of time, technology is getting more advanced and there has been a rapid growth in the concrete properties. Concrete is improving day by day. There is not yet been an exact definition of a word high strength …
