Enhancing the strength of sandcrete blocks using coarse aggregates

This current article explores the possibility of adding aggregate (10 mm size) to sandcrete mixes in order to enhance the strength of the sandcrete blocks. Four different kinds of mixes were made; the first one was used as a reference without the addition of course aggregate, and in the remaining three, course aggregates were added in percentages of 5, 10 and 15% by volume of the reference m...

Variability of visible and near-infrared (vis-NIR) diffuse spectral reflectance of cement-based solidified/ stabilized pre-treated oil-based drill cuttings

This study investigated the effects of solidification/stabilization (S/S) variables on visible and near-infrared (vis-NIR) spectral reflectance of solidified/stabilized low-temperature thermally desorbed (pre-treated) oil-based drill cuttings. Partial least squares (PLS) regression models were also developed to rapidly estimate the levels of total petroleum hydrocarbon (TPH), Cu, and Ba pres...

Reliability assessment of progressive failure of a low rise framed building on weak soil-foundation interaction

A 4-storey reinforced concrete framed buildings was modelled in 3-dimensional analysis with the same sections and loadings for both rigid and weak foundations respectively using ETABS and FORM5 Softwares in accordance with Euro code provisions. The weak foundation was initially analysed and designed as a fixed column-foundation joint and later re-analysed and redesigned as a hinged column-fo...

Evaluating mixed reality technology for architectural design and construction layout

Mixed reality (MR) technology has attracted increasing interest in the architecture and construction industry since the commercial availability of head-mounted MR devices in 2016. With its ability of overlaying digital building models in real construction sites, building owners, architects, engineers, and contractors have quickly recognized the value of MR technology in on-site architectural...

Study of physico-mechanical properties of concretes based on palm kernel shells originating from the locality of Haut Nkam in Cameroon

This study is based on the use of palm kernel shells as aggregate in the manufacture of concrete. Several (0, 25, 50, 75 and 100%) substitutions were used in the volume fraction of the aggregates. In order to evaluate the effect of this substitution, the mechanical properties at 7 and 28 days for compression was determine, 28 days for bending and then the physical properties of fresh and har...

Evaluation and selection of the quality of internal doors for buildings using building information modeling building information modeling (BIM)

The selection of building materials from various available alternatives is a critical process affected by many complicated factors. Every single element in a building has a specific function to perform. This necessitates a proper selection of material from the various available alternatives, which generally differ in their quality, performance, and cost. To make the most practical choice, th...

Potential use and benefits of automation for traffic control in roadway construction

This paper addresses the impact of using automated flagging devices in road construction instead of using construction workers. To examine the efficacy of automating this construction activity, a group of drivers with diverse characteristics/demographics was involved in the study. The diverse characteristics included gender, age, years of driving experience, and level of formal education (e....

The effect of curing condition and use of additives on compressive strength of lime/pozzolana mortar

Previous studies have shown that the obsidian pozzolana of the Sabaloka area processes a high pozzolana index. Therefore, it was chosen to study the effect of its curing condition and use of additives on the compressive strength of lime pozzolana mortar. The investigation revealed that the strength of pozzolana mortar is affected positively or increases with the curing condition (humidity, t...

Perception of professionals on factors influencing skilled labor shortages in the Nigerian construction industry

The construction industry in Nigeria plays a pivotal role in economic growth, yet it faces a critical challenge: a shortage of skilled labor. This study aims to identify the key factors influencing skilled labor availability in Nigerias construction sector and propose actionable solutions. Through an extensive literature review and distribution of questionnaires to construction professionals...
