With a background in materials engineering, Jordan provides a comprehensive overview of cement and concrete in this informative video, and explains what sets them apart from each other. Drawing on his experience working with concrete as a design-builder, he breaks down the chemical components of cement and highlights the variables that impact concrete’s strength, porosity, and workability. Jordan emphasizes the importance of the cement-sand-gravel ratio and notes that concrete has high compressive strength but low tensile strength, making it prone to cracking under tension. With clear explanations and helpful visual aids, this video is a must-watch for anyone interested in the fascinating science and practical applications of cement and concrete.
