This present research mainly focused on the behaviour of monolithically and precast portal frames made with lightweight fiber reinforced concrete. The lightweight fiber reinforced concrete (LWFRC) is achieved with Palm oil shells (POS) and glass fibers (G.F). The POS is replaced with coarse aggregates and the G.F is added to the concrete to increase ductility parameters. To reduce the further density of the concrete, replaced cement with GGBS and Palm Oil Fuel Ash (POFA) individually. All these replacements are helping the reduction of solid waste and greenhouse gases from cement Industries. Portal frames are made with M30 Grade LWFRC through replacements. All the precast frames are connected with the Dowel bar connection through the grouting. All the LWFRC frames are compared with conventional concrete frames. The palm oil shells are replaced up to 50% in coarse aggregates to diminish the density of the concrete and also to decrease the greenhouse gases from the cement industry; cement is replacing with Ground Granulated Blast Furnace Slag (GGBS) and Palm Oil Fuel Ash (POFA).

In this present research inspection on the flexural performance of reinforced concrete members formed as Industrial waste. In the inspection, Palm Oil Shells (POS) are replacing in coarse aggregates (C.A). In this research, the lightweight concrete (LWC) is attained by substituting the coarse aggregates up to 50 percent employing Palm oil shells (POS). Replacing of C.A with POS in concrete making not individual solve the complexity of disposing of this solid misuse and also helps protect natural resources. To reduce CO 2 emissions from the cement industry, the cement is partially replaced with GGBS-ground granulated blast furnace slag and POFA - palm oil fuel ash, and adding 0.5% Glass fibers (G.F) to the volume of the concrete to increase ductility properties. Beams through varying dimensions were fictional and experienced under four-point bending and also Slabs with central load are considered. Data accessible includes deflection characteristics, Ductility Index. The investigation related to flexural actions of fiber-reinforced POS concrete be equivalent to the natural concrete and the new results compare sensibly fine with the Indian code of exercise.

The present work reviews the various mineral admixtures used in concrete which modifies the concrete properties. In this study, cement is partially or completely replaced by different mineral admixtures such as fly ash, silica fume, rice husk ash, Ground Granulated Blast Furnace Slag, palm oil fuel ash and metakaolin. The strength obtained is different for different mineral admixtures by adding these to concrete. Various concrete characteristics like split tensile, compressive and flexural strength, durability, workability are presented.

Geopolymer concrete is an innovative advance in the world, in this concrete cement is fully substituted with pozzolanic materials like fly ash and GGBS. In this present study fly ash is replaced with POFA (Palm oil fuel ash) up to 25% (0%,5%,10%,15%,20%,25%), 10% of stone dust is replaced with sand. In addition to the above materials, 0.2% of polypropylene fibers were added to the volume of concrete. 2.5 ratio of sodium silicate and sodium hydroxide solutions are added as Alkali activators for 10M molarity. Initially, the specimens are oven cured 80° C for about 24hrs and after that leave for ambient curing. All the specimens stood tested after 7 and 28 days of ambient curing. The prepared POFA based geopolymer was tested for all types of mechanical properties, like compressive strength, split tensile strength, bending strength and load deflection curve. All these properties are compared with the nominal concrete.

Cement concrete is one of the utmost regularly used building materials next to water. But one tonne of cement produces 1.25 tonnes of CO 2 and pollutes the environment. To keep that in mind, in this study the cement is partially replaced with POFA up to 30% (5% equal intervals), and steel fibers are added to the volume of concrete by 0.5% apart from normal concrete. Generally, POFA is one of the Agro-Industrial garbage materials which is coming as of the palm oil industry, with the growing amount of waste produced from the different processes there has been an increasing the waste generation. Increasing intrust in the use of agro - Industrial waste to achieve the potential advantages. Comparing with cement, POFA contains a high silica content. specimens are cast with M40 grade of concrete. The prepared POFA based Fibre reinforced concrete (FRC) was tested for all types of mechanical properties, as compressive strength, split tensile strength, bending strength, and load-deflection curve. All these properties are compared with the nominal concrete.
