**Concrete & Cement Defined **

Contrary to popular belief, concrete and cement are not the same thing; cement is actually just a component of concrete. Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into the durable material with which we are all familiar.   **Match the words above to the pictures below.** **Some pictures may connect to more than one of the words.**  <span style="display: block; font-family: 'Comic Sans MS',cursive; font-size: 35px; text-align: left;">
