We used a 1000# manual lever press not automatic to test the process. We have experimented with CEB using all forms of equipment. We organized this manual press design for missionaries - paper design with a particle board mock up model shipped - then they build in their location. The CEB issue here for us was to find a knowledgeable block builder. Difficult! CEB is the most practical of the building materials I have seen. But the construction "cost effective" is deceiving. Similar to adobe but the dry mix needs to be experimented with before you build 5000 blocks - every time! The blocks go into the wall immediately no drying time concerns - press and place! The return on investment is in utility savings. But DIY is not practical accept as a personal choice - cost of equipment or that "green" block builder is over the top.
What we did with papercrete was make 7"X10"X3" pavers with an artsy embossed stamp using a CEB manual 2 to 1 press. All worked as assumed. Out of 20 blocks - 2 "crumbled" after air drying for 7 days. The rest seemed to be fine. We will get back to this next year. When we compressed the mixture the chamber was full and compresses to half ( 2 to 1). Only watery liquid came out of the press. When liquid dried it was a film of concrete. We next allowed the Papercrete mixture to set for 24 hours and then compress - lot less liquid! seems to be a better block. The CEB press process will make a block every minute - two people working moderate hard with no real rush. The messy paper crete mixture adds a few oh my gods - but not over the top.
How many blocks do you need? We assumed 5000 for a standard CEB house. 500 per day for 2 weeks? Does the papercrete need to be compressed 2 to 1? Air Dry? Solar oven dry? Can you stack them in the wall for drying? Jill is experimenting with her decorative eco blocks. This press system was borrowed and then purchased by her, an artist friend. She is making eco decorative pavers. Again, I will be talking to her next year. But she is leaning toward CEB and adobe. Papercrete is a bit of a mess!
She did compress soda cans in to pavers - she now wants me to build her a pneumatic press. Eco pavers? Artists? Green? I am teaching her husband to weld in self defense.
