Wildfires are widely recognized as a cause of mechanical damage to rocks. Nevertheless, previous research has neglected how wildfires might impact sport climbing areas. In Spain, two large affected areas between 2020 and 2021. This paper addresses the rock effects that could lead safety issues, such falls, hold deterioration, anchor damage. this study, Non-Destructive Techniques (NDTs) Ultrason...

Rammed-earth (RE) is a construction material manufactured from the soil. The soil is compacted at its optimum water content, inside a formwork to build a monolithic wall. RE material is attracting renewed interest throughout the world thanks to its sustainable characteristics: low embodied energy, substantial thermal inertia, and natural regulator of moisture; on the other hand, the existing hi...

Currently, in civil engineering, high performance concrete i.e. concretes whose minimum compression strength is equal or more than 65 MPa are increasingly used. Side effect of it is need for determination of their construction strength. In particular, recently built high performance structures suffer from sampling of drill cores. Therefore, noninvasive impact hammers – to be specific Schmitt im...

The study focused on determining the structural soundness of Carpio Hall and Federizo in Bulacan State University-Main Campus. parameters used were age building, material used, existing condition, compressive strength beams, columns, slabs two buildings. processes tests that involve include visual inspection, non – destructive testing, hypothesis interview. performance non-destructive particula...

The hammer rebound index has traditionally been solely and exclusively used to estimate the compressive strength of vibrated concrete. Its use recently extended prediction Self-Compacting Concrete (SCC) concrete produced with Recycled Aggregate (RCA). conventional hammer-rebound test is further developed in this paper, by demonstrating how it can be overall mechanical behavior SCC containing RC...

The European Standard EN 13791 provides methodologies for estimating concrete compressive strength in structures. This standard covers the testing of cores as well as the use of indirect methods, such as the rebound hammer, USPV and pull-out tests. This communication refers to a study carried out in a building where the methodologies presented in EN 13791 has been applied to estimate the in-sit...
