This paper presents a review on combining NDT techniques, such as rebound hammer and ultrasonic pulse velocity, for assessing concrete compressive strength. These methods, though being favorably not invasive easy to be extended larger number of elements, are affected by many contingency factors. The SonReb technique suggests the two methods partially offset their low reliability if considered s...

Abstract Since the cost of cement increases and pollution to environment due greenhouse effect are becoming more serious year by year, thus, dolomite fines subjected replace in concrete mix as it has lower compared cement. In this research, replacement with carried out study is 0%, 5%, 10%, 15% 25%. The grade a designed be 30. A total 45 units 150 mm x cube 30 cylindrical sample diameter height...

Recto, There were jealous demands for the recognition of Philippine sovereignty on the Bases question.

Technological processes such as forging, die forging, and pile driving are realized as a result of a collision between two bodies. After the impact the bodies’ energy transforms to plastic or elastic deformations of the colliding bodies. This paper studies both theoretically and experimentally the influence of impact parameters such as forces, accelerations, velocities, time and energy on defor...
