Q:how many cubic feet does 1 bag of cement make?? its a 80 lb bag...In your thoughts or in your experience.....thanks!!: The actual cement required for concrete is affected by the choice of the maximum coarse aggregate size. As the maximum coarse aggregate size is decreased the cement content must increase to provide the required quantity of cement paste to coat all of the aggregate particles. Assume that the proportions will be made based on one part being a cubic foot (this is convenient since a 94 lb. bag of cement is 1 cubic foot of bulk material). For a 3/4 maximum coarse aggregate, the mixture would be 1 part portland cement, 2 1/2 parts sand, 2 1/2 parts coarse aggregate, and 1/2 part water. The sum of the parts is 6 ?. In general the final volume of concrete produced will be approximately 2/3 of the sum of all the volumes included in the mixture. Therefore the approximate volume of this concrete mixture is 4.3 cubic feet. If you adjust the above mixture based on a 80 lb. bag of cement, then you will produce 3.7 cu. ft. per bag approximately. If you are talking about an 80 lb. bag of ready mix (sand garvel are already mixed in the bag), then it would be 0.60 cu.ft. per bag.

Q:how many cubic feet can i get out of 1 80lb bag of cement using sand and gravel???: 2/3 cubic feet

Q:How long does it take cement to dry?: First of all it is concrete not cement and second of all it doesn't dry, it cures. It is a chemical reaction, it does not just simply dry out like mud brick. Given that, there are too many variables to take into account, thickness, environmental conditions, the exact formula of the concrete mix, etc.

Q:I just want to ask this society now this year ridicule tank Ken Intuit old Gui tame fucking head of the government is what the background and way? Generally engage in building materials, cement construction businessmen are what people contact the circle ah? Consult by the social experience of uncle ah aunt ah ~ more: Well, most of the logistics department wish you good luck ah

Q:Was there concrete/cement in the 1880s-1890s?: Uh oh. She forgot the Romans in her History of concrete. Their concrete work is still standing. :) But I liked the story. I know you asked about the 1800's, but if you are also interested in Roman (cementitious) concrete history, here's an interesting site from the University of Santa Barbara: id-archserve.ucsb.edu/arthistory/...

Q:Say a person was in a large tub and they filled the tub with wet cement and it was to be filled right up to the persons shoulders leaving his neck and head sticking out? Like after the block of cement hardens? Would the person die?just curious.: DEATH happens,dear. Crushing the chest kills. Haven't you ever picked up even a small sack of *dry*cement?

Q:Okay, I made a boo boo and drove into a short brick wall (decorative) next to my driveway. I knocked a chunk of about 4 bricks off and now I want to simply stick them back on for as little as possible (labor and cost). The chunk sits nicely on the rest on the wall where it was and really shouldn't go anywhere, but I just want to have a nice fix. Could I just squirt some Great Stuff in there and hold it down for a few minutes?I was just hoping to use something around the house (not cement)Thank you so much in advance!: Clean all of the surfaces well. Then use a two part epoxy to hold the broken parts together. If you are in a cold area of the country, wait until much warmer to do this.

Q:i recently removed the tilling from my basement floor and now my basement is just plain cement flooring. What are the steps i need to take to tile over it?: since you have concrete already you wont need concrete or fiber board. you can just lay right over it. go to the harware store, get your thinset,tile and grout. put down your thinset with an edged trowel,square your tiles with tile spacers(dont forget to square the tile run with the rest of the room) then sponge in your grout.

Q:quot;What date was cement made?: 1.Cement is made by heating powdered limestone and clay. 2.It is used in mortar and concrete - mortar is used to join bricks together and is made by mixing cement with sand and water - concrete is made by mixing cement with sand, water and aggregate (crushed rock) 3.it sets and hardens quickly so building is faster. 4. Portland cement mortar was invented in 1794 and patented in 1824. It gained in popularity over lime mortar by the latter part of the 19th century and by 1930 has all but replaced lime mortar for new construction. Lime mortar was first used in Mesopotamia and was made by heating up limestone to drive out the water, then grinding it to a powder, which had sand added to it for greater strength. To use it, water was mixed to it to form a paste which slowly hardens. It was used in the Pyramids.

Q:how is cement prepaed? what are the uses and different types of cement?: I've been in exactly the same situation. We live on the edge of nowhere and can't get delivered concrete. We poured our greenhouse floor, using Portland premix cement and a mixer. Our mixer is slightly smaller than yours. We used extra water in the mix so it would stay workable longer. Bad idea! The floor did fine until the first winter. It then split, chipped cracked and, well, you get the picture. We ended up redoing it. The second time we divided the floor into three sections. Each section had its own small 3/8 rebar web placed 2 above ground in a 4 floor. We supported the web by driving 10 pieces of 3/8 rebar into the ground and wire to hold the web to them. Lastly, on the sides where the adjoining sections would go, we used 1 x 6 pieces of redwood. We drilled them and ran rebar through to the web – leaving 2' sticking out for attaching the new sections. That piece sticking out was attached to the next section's rebar web. It has been there for several years now, and has no cracks at all. Our temperatures range from 105°F in summer to -40°F in winter. I put a link in to show how to determine how many cubic yards of concrete you'll need. Good luck!
