Development of Papercrete due to Paper mixing ratio

performed to solve the original mixing design ratio of papercrete and to obtain some mechanical properties of papercrete such as strength, Elastic Modulus, shrinkage and failure mode First, based on general papercrete mix design, paper-cement ratio and sand-cement ratio were fixed about 0.6 and 0.7,

What Are the Strongest Types of Concrete?

But water makes the concrete workable; the typical water/cement ratio balances strength and workability. Aggregate is also a factor in the strength of concrete; a strong concrete mix has a low water/cement ratio and strong aggregate. Concrete reaches its full strength through the chemical reaction between cement and water, called hydration.
