Prediction of Compressive strength of Periwinkle Shell Aggregate Concrete Using a Quadratic Polynomial Function
Abstract: In this study, a mathematical model is developed to predict the compressive strength of normal concrete made with periwinkle shell as coarse aggregate using a quadratic polynomial function. The response function is expressed as a multivariable function of the proportions of the component materials (water, ordinary Portland cement, sand and periwinkle shell).

Potential of Limestone Powder in the Production of Self Compacting Concrete
Abstract: Self-compacting concrete (SCC) is a cutting-edge building material. It's a smooth, durable concrete that fills the formwork completely. The SCC needs a lot of powder to perform well (mostly cement). However, increasing the cement content is impractical and may result in greater hydration heat and drying shrinkage. This project studies the effect of limestone powder (LSP) on the fresh and hardened appearances of SCC. To evaluate the samples with and …

Prediction of Circular Frequency of Precast Concrete Piles with Distributed Mass by Resonance Moment–Displacement Approach
Abstract: This paper presents the results of circular natural frequency of single piles from critical buckling load by resonance moment-displacement approach. The support end conditions considered are pinned-pinned, fixed-fixed, and fixed-pinned respectively. It was assumed that resonance moment occurs when the bending moment diagram is made equal to zero at the supports while the resonance displacement is the sum total deflections resulting from the system reduction to an equivalent pinned-pinned system. …
