The advantage of using expansive cements is to induce stresses large enough to compensate for drying shrinkage stresses and minimize cracking. 8. High-strength concrete is made by lowering the water-cement (w/c) ratio to 0.35 or lower. 9. To compensate for the reduced workability, superplasticizers are commonly added to high-strength mixtures. 10.
