This paper presents the results of a mathematical model developed for predicting the 28-day compressive strength of foamed aerated concrete containing pulverised bone as partial replacement of cement for the purpose of ...

The African Regional Conference on Engineering Education (ARCEE) provides a forum for all the stakeholders in engineering and technology education within the region to come together and deliberate on common problems within ...

Traffic congestion occur as more vehicles ply the road and result in reduced travel speed, increased travel time, unnecessary queuing, obstruction on travel path and impediment to traffic flow. Thirteen per cent of greenhouse ...

Lagos-Ibadan Expressway is infamous for high accident rate, leading to loss of innocent lives. The contributions of human, road, vehicle and environmental factors to these road accidents were examined. A comprehensive ...

Basic oxygen furnace (BOF) slag aggregates exhibit several favourable technical and environmental characteristics compared with natural stone aggregates, making them potentially valuable road construction materials. BOF ...

In this study, the behaviour of bamboo reinforced concrete beams was examined under a third point loading. Each beam was simply supported over an effective span of 600mm. The results showed that the behaviour of the beams ...

Abstract: The science and technique of substituting laterite for fine aggregate ill normal concrete work is rapidly increasing ill Nigeria. Studies Oil laterized concrete elements have been devoted primarily to observation ...

This paper reports on the behaviour of bamboo reinforced concrete columns under the applied axial loads. 150x150x1000mm columns were cast using 1:2:4 mix with water/cement ratio of 0.65. The bamboo content was varied from ...

The science and technique of substituting laterite for fine aggregate ill normal concrete work is rapidly increasing ill Nigeria. Studies Oil laterized concrete elements have been devoted primarily to observation under ...

This study presents the results of the investigation of the response of lightweight concrete to elevated temperature. Available literature indicates that research works have not been carried out in this area. ...

Reports and news on failure due to corrosion degradation of structures ill aggressive environments are common occurrences in literature nowadays. This paper presents deterioration pattern of concrete structures in a coastal ...

Three types of fine aggregates are investigated for making concrete. namely sand for normal concrete, granite and laterite fines. The properties considered are compressive and tensile strengths. Three mix proportions of ...

This study investigated chemical, physical-mechanical and environmental characteristics of weathered blast furnace slag (WBFS) and freshly produced slag (FBFS) for their potential utilisation as granular road base and ...

Oil palm trees are abundant in Nigeria but they are hardly used for structural purposes, except in some rural areas where they are used as roof trusses, floor joists and occassionally columns.' In this paper tensile ...

This paper identified and documented the deterioration pattern of concrete structures in Lagos coastal environment. It also determined the concentrations of chloride ions and their effects on reinforcements in concrete ...

One of the factors which affect road failure (which is a common feature of the tropical environment) is the soil used as sub-base material. Soils (usually obtained from borrow pits) used as sub-base material contain a ...

The construction industry in Nigeria is presently operating at a low ebb due mainly to the high cost of construction materials. The use of local materials has been advocated as a step towards solving this problem. This ...

In this study, seven grain size ranges of granite fines were used: 4.75 - 3.35mm, 3.35 - 2.36mm, 2.36 - 1.70mm, 1.70 - 1.18mm, 1.18 - 0.30mm, 0.30 - 0.063mm and 4.75 - 0.063mm (those containing all grain sizes). The ...
