Effect of edge oxidized graphene oxide on micro and macro mechanical properties and microstructure of cement paste
Published in International Journal of Materials Research
The effects of edge-oxidized graphene oxide (EOGO) on the micro–macro mechanical properties and microstructure of cement pastes were evaluated. Three different cement pastes with EOGO contents of 0 %, 0.05 %, and 0.5 % were prepared, and the compressive strengths and different ages were examined. In addition, the nanomechanical properties of the pa...
Experimental study on self-compacting concrete with replacement of coarse aggregate by light expanded clay aggregate
Published in IOP Conference Series: Earth and Environmental Science
The present study deals with fresh and hardened concrete properties of self-compacting concrete while carrying several trial mixes with a variety of water binder ratio and super-plasticizer content and finally achieved a trail mix with satisfying the flow properties as slump flow, V-funnel, and L-box test apparatus values are obtained within the li...
Performance evaluation of glass fiber reinforced high-performance concrete with silica fume and nano-silica
Published in IOP Conference Series: Earth and Environmental Science
Investigators all around the globe are making unrivaled concrete by varying the proportions and admixtures. Fiber-reinforced concrete has various applications in structural components. Some of the fibers like glass, carbon, polypropylene, and aramid fibers give an improvement in generous properties like hardened, durability, stiffness, toughness, s...
Experimental study and theoretical modeling for the compressive stress-strain relationship of multi-scale hybrid fiber-r...
In order to better match the multi-level structural characteristics and multi-scale fracture process of cementitious composite, multi-scale hybrid fiber-reinforced strain hardening cementitious composite (MsHySHCC) was designed by adding hooked steel fiber and calcium carbonate (CaCO3) whisker into conventional polyvinyl alcohol (PVA) fiber-reinfor...
Physico-chemical, mineralogical, and technological characterization of stabilized clay bricks for restoration of Kasbah ...
Due to ageing, the unfired brick masonry may detach and fall off, or deteriorate to such an extent that it becomes necessary to restore them. Such is the case, for instance, of the Ksar of Ait Benhadou in Ouarzazate, Morocco. Our study aims to provide compatible and sustainable earthen bricks to restore this monument. Samples were collected from fa...
Investigation on the characteristics of self-cured geopolymer concrete using GBFS sand
Published in Innovative Infrastructure Solutions
For some years now, scarcity of natural aggregates and an increase in waste by-products have been the biggest problems facing the construction industry. Therefore, the present study investigated the potential use of granulated blast furnace slag (GBFS) sand to substitute the river sand in geopolymer concrete. The attempts have also been undertaken ...
Utilization of riverbed silt and subsoil of Gopalganj for masonry bricks incorporating internal fuel and comparison of t...
Published in Innovative Infrastructure Solutions
Agricultural topsoil is the most common raw material for making clay bricks in Bangladesh because of its abundance and prehistoric tradition. This practice of the bygone age is steadily pushing the environment toward the risk of fertile soil depletion. At the same time, the largest delta of this world gathers tons of sediment during the monsoon whi...
Effects of vermiculite on in-situ thermal behaviour, microstructure, physical and mechanical properties of fired clay br...
Vermiculite is a hydrous clay mineral that occasionally occurs in raw materials for brickmaking. The presence of vermiculite affects the drying and firing processes of brick production; thus, the functions of this clay mineral should be clarified. In this study, vermiculite from 0 wt% to 30 wt% have been added to clay mixtures for brick button firi...
Enhancing corrosion resistance of RC pipes using geopolymer mixes when subjected to aggressive environment
Published in Journal of Engineering and Applied Science
The durability of reinforced concrete (RC) pipes depends upon the corrosion resistance of the reinforcing steel and the resistance of concrete mixes against an aggressive environment. This research paper aims to compare the performance of R.C. pipes made of ordinary Portland cement (OPC) concrete mixtures with others made of two different geopolyme...
