View AllThe present paper provides an overview on test techniques for determining tensile and fracture toughness properties under dynamic conditions and examples of effects of dynamic rates on tensile properties and fracture toughness, as well as structural assessment considerations.
View AllTensile strength of concrete the actual tensile strength of cement paste or similar brittle material as that of stone is very much lower than the theoretical strength estimated on the basis of molecular cohesion of the atomic structure and calculated from the energy required to create the new surfaces by fracture of a perfectly homogeneous.

View AllThe strength can be improved further by reducing the maximum size of coarse aggregate and increasing cement content.For the production of high strength concrete, it is recommended to make trial mixes before construction.A pre-construction meeting with the contractor is also important.
View AllTo increasing the compressive strength of concrete, we must increase cement and decrease water quantity.For example, m15 grade of concrete when we use50 kg of cement,480 kg aggregates and32 liters water we get15nsq.Mm compressive strength after28 days by15 cm.Cube test.
View AllCharacteristics of dynamic tensilecompressive strength from fig.8, it can be seen that the concrete strength under biaxial tensioncompression increases with the increasing of strain rate, and the increasing degree of uniaxial tension is the smallest, in table.
View AllThe different effects on concrete strength with age are explained in this section.Variation of concrete strength with time.As per studies and researches, the compressive strength of the concrete will increase with age.

View AllThe research object of the paper is cement paste with the particulate reinforcement of basalt fiber.Regardless of fibers length at the same fiber cement mix workability and cement consumption equality compressive solidity of the specimens is reduced with increasing fiber content.This is due to the necessity to increase the water-cement ratio to obtain a given workability.
View AllHigh-strength concrete is specified where reduced weight is important or where architectural considerations call for small support elements.By carrying loads more efficiently than normal-strength concrete, high-strength concrete also reduces the total amount of material placed and lowers the overall cost of the structure.
