Concrete

Concrete is an ingredient utilized for rocket silos, refined concrete, artillery turrets and facilities relating to nuclear material (reactors and centrifuges). Concrete serves as path with more advanced bonuses compared with stone bricks. Concrete increases walking speed by 40% and decreases vehicle rolling resistance, allowing for extra acceleration and top speed, although each vehicle is affected differently; the tank is only affected by a 20% bonus, for example. Concrete has no effect on the movement speed of enemies. When placed, it reduces the pollution absorption of ground to zero.

In Space Age, on the planet Aquilo, concrete is essential for construction. In order to place many buildings and structures on icy terrain, concrete (or one of its derivatives) must first be placed on top of the floating ice platform before the building can be placed.
