Research findings have reported a behavioural relationship between the splitting tensile strength and compressive of concretes. This work studied both experimental analytical relationships that exist vibrated concrete (VC) self compacting (SCC) similar grades. Both types were designed to achieve target 20 N/mm2, 30 N/mm2 40 at 28 days. The properties measured on cylindrical specimens 150 mm diameter × 300 length 28-days using compression testing machine. tested seven different models...

Partial replacement of cement with eco-friendly pozzolanic materials, such as waste glass powder (WGP) and metakaolin (MK), offers a sustainable approach to improving the service life self-compacting concrete (SCC). This study evaluates effects WGP MK, individually (binary) combined (ternary), partial replacements for cement. Concrete mixes were assessed workability, mechanical properties, microstructure. Workability tests showed enhances flow while MK reduces them; however, their use at 15%...

This study was carried out to assess the punching shear behavior of flat slabs considering use various column shapes such as L, T, and Cruciform support. The slab floor system is becoming most adopted in structures ranging from medium-rise skyscrapers, garages, factories, airports, etc. Although this field study, research has been over decade, limited considerations were made for compound geometries. Finite Element modelling software Abaqus used development a numerical model capable...

The durability of a building is determined to great extent by the quality materials used in its construction. Sandcrete block major material Nigeria. This research assessed blocks produced Adeta, Ilorin West Local Go vernment Area Kwara State, Eight factories were selected from study area and their measured for water absorption ratios compressive strengths compared with Nigerian Industrial Standards (NIS) specifications. Six samples each size 450mm x 225mm per factory tested. Experimental...

The rising cost of concrete production due to the global recession in world economy caused by COVID-19 pandemic and greenhouse gases emitted cement has necessitated need for alternative materials cement. In this study, bamboo strips steel rebars were used as reinforcements a ternary blended determine their strength properties. alignment with standard requirements testing, specimens tested at curing ages 7, 14 28 days compressive, splitting tensile flexural strengths. morphological bond...

The study developed an Advanced Public Transportation System (APTS) software package that serves as intelligent movement system for captive commuters. Although a typical APTS has Automated Trip Scheduling (ATSS), Digital Geographic Database (DGD), and Vehicle Location Equipment (AVLE) subsystems, the fact vehicles in area are not equipped with AVLE made authors to design only ATSS DGD components. subsystem specific objectives of reducing commuters waiting time at bus terminals, automating...

Bridge Scour is the localized loss of geomaterials around foundation a bridge as result movement water it. great risk to stability bridge’s foundation, thus leading collapse, lives and setback in nation’s socio-economic life. Artificial Neural Networks (ANN) are collections simple, highly connected processing elements that learn according sets input parameters use simulate networks nerve cells humans or animal central nervous system. The Asa Dam Bridge, one longest bridges Ilorin, Kwara...

Calcined clay, a widely studied supplementary cementitious material, has shown positive impacts on concrete's microstructural properties, strength development, and durability. The variation in raw clay mineral concentration across different locations influences the optimal calcination temperature needed to activate its pozzolanic reactivity. This investigation focuses studying effects of characterization reactivity Nigerian Kaolinite clay. was calcined at temperatures ranging from 600˚C...

Concrete, a fundamental construction material, consists of aggregates, water, cement, and additives. Unfortunately, the large-scale production cement is major contributor to carbon dioxide (CO 2 ) emissions, primarily from manufacturing process consumption fossil fuels. This not only incurs environmental costs associated with global warming but also depletes vital limestone deposits. To mitigate these issues, this study aims explore optimal utilization Guinea Corn Husk Ash (GCHA) Rice (RHA)...

Earthquake is a natural phenomenon which caused by sudden release of energy in the Earth's crust that creates seismic waves. Seismic response an overhead water tank with varying foundation types subjected to five different earthquake accelerograms was simulated using Time History Analysis. Tank responses observed includes base shear, moment and displacement at some joints. The maximum shear obtained 9.521E+03 kN 1.093E+04 for pinned fixed foundations respectively. displacements three...

The need for habitable and affordable shelter cannot be overemphasized but the high cost of components such as hollow sandcrete blocks, bricks etc. posed a challenge to our ability access shelter. Utilization already discarded waste foundry sand (WFS) eco-friendly construction material production will save preserve environment. In this study, impact locally available partial substitute sharp in blocks was investigated. Sharp partially substituted with WFS at 0, 10, 20 30%. A mix ratio 1:6...

This study utilized Finite Element Method (FEM) to analyse the structural behaviour and failure modes of Reinforced Self Compacting Concrete (RSCC) deep beams. Eighteen beam specimens subjected four-point loadings were modelled analyzed using Abaqus modelling tool. Damage plasticity model was used characterised nonlinear concrete material while linear elastic, linear-plastic-hardening represented reinforcing steel behaviour. The results finite compared with four different Strut Tie Models...
