yeah i know portland is the type. ive been looking everywhere, and apparently quickcrete portland type I is the only kind found like anywhere within a 100 mile radius of my house. so my dad knows some people through work and hes going to try and get me the type i need. i just need to know what kind. so general consensus is that its type III that im looking for? sweet. ill look around a little more to make sure but hopefully if i cant find it hell be able to.
