Sorption characteristics of cement composite reinforced with some locally available lignocellulosic materials in Nigeria
The aim of this study was to investigate the sorption property of wood cement composite produced from bagasse (Saccharum officinarum), bamboo (Bambusa vulgaris) and coir (Cocos nucifera L). The mass of the fibre varies from 1 to 6% of the mass of cement. The result indicated that the mass fraction has significant effect on the sorption properties of the composites....

Simplified method of strengthening RC continuous T beam in the hogging zone using carbon fiber reinforced polymer laminate – A numerical investigation
Though Reinforced Concrete (RC) continuous beams are vastly used in civil engineering, little experimental work on repairing and strengthening of continuous T beams has been carried out; especially, experiments on strengthening the hogging zone of continuous beams are very rare. This paper attempts to address an important practical issue which is not considered in existing conventional strengthening...

Reinforcing efficiency of glass fibres in low volume class F fly ash concrete
This study reports the reinforcing efficiency of glass fibre addition in the low volume fly ash concrete upto 25% cement replacement level. Micro mechanical action of glass fibres in fly ash concrete are discussed with respect to different percentage of glass fibre addition. Glass fibres in concrete improves the matrix densification, refinement of microstructure, reduction of voids, minimize cracking due to...

Behavior of impervious facing system in zone semi arid in absence of the thermal protection Bouhnifia dam (Algeria)
The bituminous concrete mask was the water barrier system of Bouhnifia dam "Algeria”. It was applied on the upstream slope. The mask risked to be unstable because of the sunlight temperatures which can reach (65°C). So, it was covered with a thermal protection which demands a periodic renovation. This solution was very expensive. To avoid these costs, one tried to test the stability of the mask...

Assessment of environmental hazards: Linking borrow pits, gully erosion, and road failure
Highway failure linked to the action of erosion initiated by active or abandoned borrow pits in no small measure affects environmental quality and safety. This study has investigated the Owerri-Okigwe-Enugu highway, Nigeria. Environmental assessment of the study area through photographs showed prevalence of landslides, at risk structures, and motor accidents. Soil samples were collected at three abandoned...

Load-settlement test of full-scale foundation on concrete-grid reinforced soil
Result of field test on load-settlement of full-scale foundation, resting on soil reinforced with concrete-grid is presented. The test was carried out at 3 different points within a construction site in Minsk, Belarus. The test points were characterized by different soil conditions below the reinforced base. Result of the study shows that, the use of concrete-grid as reinforcement for subsoil base under...
