Concrete which is widely used material in the construction industry, has a carbon footprint. Approximately 10% of global Carbon Dioxide (CO2) gas emitted during production cement vital ingredient concrete. The increase affects warming and climate change. Therefore, many have attempts been made to develop green sustainable concrete by utilizing different waste materials. With utilization materials as replacement, CO2 emissions can be reduced well resolve environmental issues that inhabitants...

With the reduction in permanent load on structure and excellent insulation properties, lightweight foamed concrete is a potential thermal insulating building material to counter urban heat island effect, which increases temperature of areas due concentration infrastructures constructed using conventional that absorbs solar radiation.

Through concrete, air voids various...

As almost half of the world's population now lives in urban areas, raise temperature these areas has necessitated development thermal insulating material. Conventional concrete absorbs solar radiation during daytime while releasing it at night causing areas. The conductivity 2200 kg/m3 density conventional is 1.6 W/mK. Higher value, greater heat flow through To reduce this transfer, construction industry turned to lightweight foamed concrete. Foamed concrete, due its air voids, gives...

The release of carbon dioxide (CO2) during the production cement and increase in waste generation has allowed construction to focus on sustainability by replacing with agricultural resources such as Palm Oil Fuel Ash (POFA) Eggshell Powder (ESP).This experimental study focuses developing sustainable foamed concrete incorporating high content POFA ESP replacement aim conversion, reduction natural depletion, CO2 emissions cleaner production.Cement was replaced using 30 35% 5 15% weight...

Wind-induced loads and motions play a critical role in designing tall buildings their lateral structural systems. Building configuration represented by its outer shape is key parameter determining these responses. However, contemporary architecture trends towards creating taller with more complex geometrical shapes to offer unique designs that become signature on the map of world. As result, evaluating wind-induced such structures becomes challenging be evaluated predicted. This paper...

Agro-industrial wastes incorporating supplementary cementitious materials (SCMs) regarded as sustainable efforts to reduce environmental impact generated by agricultural residual byproduct well the production of cement.

Quasi static finite element analysis (FEA) was conducted on precast lightweight foamed concrete sandwich panel (PLFP) using ABAQUS/Explicit module to study its structural behavior. The PLFP subjected axial load simulated under perfect and imperfect conditions. Results from the FEA were validated with experimental data accurately. The produced ultimate load carrying capacity, damage criteria and vertical horizontal displacement. It found that proposed model for with imperfection...

Abstract Concrete is the most versatile product used as building material in world’s construction industry, and it generates carbon to atmosphere. In manufacturing of cement, 8% 10% global dioxide (CO 2 ) gas generated. The maximum utilization cement contributes warming climate change. Therefore, many scholars have conducted a research develop green sustainable concrete incorporating different waste materials. By utilizing materials replacement, CO emissions will decrease. This paper reviews...

The fabrication process of concrete in the construction has caused carbon dioxide released into atmosphere subsequently increases footprint.Meanwhile, large sum agricultural waste are generated such as palm oil fuel ash (POFA) and eggshell powder (ESP).Incorporation supplementary cementitious materials by capitalizing regarded sustainable effort to reduce environmental impact.In this study, foamed (FC-POFA-ES) was incorporated with 20% POFA, 5% 10% ESP.Beam specimens 20 POFA 10 ESP +14% 05...
