Study of Self Compacting Geopolymer Concrete (SCGC) haunch beams at monotonic loading and loading-unloading scheme

monotonic and cyclic loading of new frp reinforced concrete cantilever beams

frps (fiber reinforced polymer) possess many favorable characteristics suitable and applicable for construction industry when compared with steel reinforcement. there are new ideas to use frps as longitudinal or transverse reinforcement for new concrete elements particularly for bridge decks or beams. although high tensile strength of frp is main characteristic for applications at both areas, i...

Self-compacting Concrete (scc)

Effects of Loading Rate on Reinforced Concrete Beams

The effects of loading rate on the reinforced concrete beams are experimentally studied in the present paper. Firstly, the effects of strain rate on the different grades of concrete are investigated using the electro-hydraulic servo-controlled testing system at the strain rate that might be experienced during earthquakes. Based on the test results, the dynamic increasing factors (DIF) of concre...

Behaviour of Reinforced Fibrous Concrete Beams under Reversed Cyclic Loading

When earthquakes occur, energy released by the earthquake gets induced into the structure as ground motion and this energy has to be dissipated for safety reasons. To release seismic energy, the structure should damage in such a way that on one hand, collapse of structure should not occur and on the other hand, after the earthquake, damage should be economically feasible to repair. To avoid the...

Compressive Strength and Workability Characteristics of Low-Calcium Fly ash-based Self-Compacting Geopolymer Concrete

Due to growing environmental concerns of the cement industry, alternative cement technologies have become an area of increasing interest. It is now believed that new binders are indispensable for enhanced environmental and durability performance. Self-compacting Geopolymer concrete is an innovative method and improved way of concreting operation that does not require vibration for placing it an...
