Effect of Temperature and Age of Concrete on Strength – Porosity Relation	2004	4	.pdf	application/pdf	2491	139	65	180 days confirms generally accepted hypothesis that with increasing porosity strength of the concrete decreases. AP04_1.vp 1 Introduction As known from experimental studies of concrete behav- iour at room temperature, there is a close correspondence between compressive strength S and its porosity P. Commonly this dependence is decreasing function, i.e. strength S de- creases with porosity P. There are many attempts to express the relation S � S(P) in an analytical form.	cache/ap-516.pdf	txt/ap-516.txt
