Abstract :

Lightweight Concrete Can Be Defined As A Type Of Concrete Which Includes An Expanding Agent In That It Increases The Volume Of The Mixture While Giving Additional Qualities Such As Mailability And Lessened The Dead Weight. It Is Lighter Than The Conventional Concrete. The Main Specialties Of Lightweight Concrete Are Its Low Density And Thermal Conductivity. Its Advantages Are That There Is A Reduction Of Dead Load, Faster Building Rates In Construction And Lower Haulage And Handling Costs. Lightweight Concrete Maintains Its Large Voids And Not Forming Laitance Layers Or Cement Films When Placed On The Wall. This Research Was Based On The Performance Of Aerated Lightweight Concrete. However, Sufficient Water Cement Ratio Is Vital To Produce Adequate Cohesion Between Cement And Water. Insufficient Water Can Cause Lack Of Cohesion Between Particles, Thus Loss In Strength Of Concrete. Likewise Too Much Water Can Cause Cement To Run Off Aggregate To Form Laitance Layers, Subsequently Weakens In Strength. Therefore, This Fundamental Report Is Prepared To Study Activities And Progress Of The Lightweight Concrete. Focused Were On The Properties Of Lightweight Concrete Such As Compressive Strength, Water Absorption And Density And Its Applications In Various Fields Of Civil Engineering Construction. The Present Day World Is Witnessing Construction Of Very Challenging And Difficult Civil Engineering Structures. In This Study Comparison Has Been Made Between Plain Cement Concrete And Light Weight Concrete Having Different Proportion Of Aggregates And Admixtures. I.e., Expanded Clay Aggregates: 0%, 25%, 50%, 75% And 100% With Coarse Aggregate, Silica Fumes 10% And PVA (Poly Vinyl Alcohol) 1.6% Of Constant Replacement With Cement And Water Respectively. It Helps To Increase The Volume Of Concrete And Hence Reduce The Weight. In Design Of Concrete Structures, Light Weight Concrete Plays A Prominent Role In Reducing The Density And To Increase The Thermal Insulation. These May Relate Of Both Structural Integrity & Serviceability. More Environmental And Economical Benefits Can Be Achieved If Waste Materials Can Be Used To Replace The Fine Light Weight Aggregate.
