the x of a given conc mix is governed primarily by its w/c ratio
strength
adding more than the spec amount of water to the conc mix generally result in greater x and x strength
shrinkage, strength
the term w/cm refers to
water/cement plus pozzolan ratio
conc mixes with lower w/c ratios are x and more x than conc with higher w/c ratios
stronger, more durable
most concretes have a w/cm ratio between abt x and x
0.4, 0.7
is the following statement true or false: the amount of cement plus pozzolan indicates the total amount of cementitious material (cm)
