This study evaluates the impact of geographic source variation of Burnt Pulverized Chikoko (BPC) clay on the compressive strength characteristics of concrete Chikoko clay was sourced from Okrika (Rivers State) and Ogbia (Bayelsa State), both in the Niger Delta region of Nigeria, and processed through calcination into BPC. The material was incorporated as an admixture in concrete at varying proportions (0%, 5%, 10%, 15%, and 20%) using two mix ratios (1:1.5:3 and 1:2:4) with a constant water ceme...

Rockfall is a common mountain geological disaster. It has the characteristics of high release energy, sudden and strong disasters. In order to effectively prevent the occurrence of geological disasters such as rockfall. This paper takes the perilous rock mass of Baiyan Mountain in Guilin as the research object. The perilous rock mass of Baiyan Mountain is classified and numbered and the corresponding stability evaluation standard is formulated for the Baiyan Mountain perilous rock mass group. Ba...

Red clay is prone to stability problems in engineering due to its high porosity ratio, strong hydrophilicity, and high sensitivity of strength to water content. Traditional improvement materials (such as cement and lime) have significant effects but suffer from drawbacks like high energy consumption, high carbon emissions, and environmental damage. To explore a green and sustainable soil improvement method, this study selected three biopolymers—xanthan gum, guar gum, and carrageenan—as modifiers...

An architectural tour of our rural areas around the world showcases unique expressions of cultural identity through our buildings, spatial layouts, and decorations, often overshadowed in urban environments; Chad is no exception. Authors present their strategies for promoting local identities. In Chad, the architect-urban planner Senoussi Ahmat Senoussi oversees the women of Gaoui as they enhance their techniques in earthen decoration. Also, the architect ROGER Boriata studied the variation of tr...

The general layout of rail transit depots should be designed based on planning requirements, site constraints, and track connection conditions. It aims to ensure smooth and efficient train operation and maintenance while considering factors such as over-track property development and land use value. A comparative analysis of multiple schemes is essential. Taking a depot of a specific line in Shanghai’s rail transit system as an example, this paper proposes three layout schemes with varying posit...
