High strength concrete is very widely used today to support the construction of buildings, roads, dams, bridges and so on. To make high quality concrete, additional material is needed as a concrete mixture, the added material today is very much in the market as well as added ingredients derived from fly ash, and rice husk, especially rice husk is most widely used as a mixture in making concrete, due to the chemical content of SiO2 contained in rice husk ash. In this study we made high strength concrete using ash derived from waste paper. Paper ash was burned manually and then filtered using sieve number 150. Paper ash was then tested for its chemical content. The results of the chemical content test derived from paper waste ash have a CaO of 92.70 while SiO2 is only 2.63%. The making of test specimens was made as many as 90 pieces with some additional variations of noble ash from 0%, 5%, 10%, 15%, 20%, and 25%. Concrete compressive strength test results with a code of 0% could not achieve the quality plan of 45 MPa, while the addition of ash by 5% reached 41 MPa compressive strength more, the highest compressive strength produced by a mixture of 10% paper ash which achieved a compressive strength of more than 45 MPa plan. Whereas specimens with a mixture of 15%, 20%, and 25% produce concrete with compressive strength below 36 MPa. From the results of the study it can be concluded that the use of 5% and 10% waste paper ash can increase the compressive strength of concrete. Ash from paper waste can be an alternative material added to the concrete mixture.

“…The 75% volume cover by the binder, sand, water and foaming agent the remaining 25% volume cover by air (Aldrigde 2005). The foamed accomplishes to enlarge the concrete, increase the volume of blend, self-compaction and lighter in weight (Lakhiar et al, 2018a andAghaee et al, 2014). In general words, foamed concrete is preferred as innovative and sustainable construction product for its benefits mentioned above.…”

Foamed concrete is considered as light weight concrete which possesses lot of benefits in context of speedy construction, light weight and durability. In this study, foamed concrete beam, containing the plastic fibers were analyzed under flexural load by experimentally and also by finite element analysis in terms of load bearing capacity, load deflection profile and cracking pattern. The Finite element analysis (FEA) was conducted by utilizing ABAQUS software to simulate the foamed concrete beam under flexure load. The beam consist the dimension was 100mm thickness, 200mm breadth, 1000 mm length. The experimental and FEA outcomes were compared in context of the beam's ultimate load, load deflection and cracking pattern. The outcomes demonstrate that the difference between ultimate load was 5 to 8% between FEA and experimental results whereas the maximum deflection was 3 to 7 % decreased in FEA compare to the experimental analysis. The parametric was conducted by changing the reinforcement area the results demonstrates that by increasing the main reinforcement area the ultimate load was rises and deflection was decreases compare to the control sample.

Precast system has great advantages in terms of its speed of construction, strength and durability. In this research, Precast Lightweight Aerated Concrete Panel, PACP, incorporating polypropylene fibers were utilized and tested to analyze its structural behavior under flexural load. Finite element analysis (FEA) using LUSAS software was utilized to simulate the PACP models under flexure load adopting nonlinear and transient analysis. The dimension of PACP panel was 200mm thickness, 500mm breadth, 1400 mm length. The FEA results were com-pared to theoretical results in terms of the panel’s ultimate load. Different thicknesses and reinforcement diameters were utilized in the FEM simulations to determine the optimum values for both parameters which confirm the stability of the panel. The outcomes demonstrated that 300 mm thickness is the optimum thickness while 12 mm diameter was the optimum size of reinforcement in the PACP panel.
