Super maxximum plus concrete

SMPC is used on city planets like Centera and Earth. It is a very strong concrete that lasts for thousands of centuries, it was created by MAXXIMUM and is the strongest concrete currently. SMPC is also used on some planets that are known for having very dangerous villains that like to destroy cities. On these planets, SMPC is not only used for sidewalks, but also for buildings and other things because it prevents destruction from many types of lasers and weaponry.
