Q: how to calculate quantity of cement in concrete?: You have two ways to determine the amount of cement in a concrete. 1. From the concrete mix design. The mix design contains the amount of cement, as well as the sand, stone, and admixtures, used in a concrete. You also can get the amount of cement from the batch tickets. If you luck out, a few concrete plants use batch tickets as delivery tickets and you may find it there. However, batch tickets and delivery tickets are typically different. 2. Perform a chemical analysis on the concrete. Take a couple of cores and send then to an experienced forensic concrete testing lab. By using chemistry and compression strength of the cores, the cement content of a concrete sample can be determined. Cheers and good luck!

Q: ingredients of cement?: Do you mean concrete, that holds things together or for roads and bridges? It can be confusing because many call concrete cement. Concrete that is being mixed in the drum truck is made of cement (a dust), rock, sand, water, air. For some projects they will add flyash or other lighter weight additives and lower the actual amount of cement included.

Q: i am having a fence installed, i have quotes from 2 different contractors... one pounds the posts into the ground, the other cements each post into the ground, how deep either go i am not sure... but which way would be more secure long term? the posts are the same as used for a chain link fence (steel posts)... thanks: Dig hole pour in cement and then set the post always good Idea to sink post into ground a ways so it will stand up while cement dries this is the best way. Cheapest and easiest way is get big hammer and drive into ground but those fences have bad habit of falling over.

Q: We have an awkward spot in our basement heading down the stairs. We barely have enough spaace to bring bigger items down. We would like to put a 3/4 drywall and glue it to the wall. Is this possible? Can I just use liquid nails?: Maybe you could get away with 1/4 drywall instead if space is tight. They do have liquid nails for that application, I think. Another option rather than drywall, might be an inexpensive prefinished beadboard. It's about $15 at homedepot or menards. The reason I suggest that is because if the small space is hard to move things through, the drywall will get dinged pretty easily. And at my house, it seems I am constantly patching holes in the drywall in my hallway going upstairs. If you're worried about it holding and really are just trying to get around the difficulty of mudding the walls, you can add wood moldings at the seams and where it butts to the ceiling-- again attaching with liquid nails or cement screws. They do make cement screws that don't require the plastic insert-- although, you still have to predrill the holes with the bit that ussually comes in the box.

Q: Which type of cement: portland cement, 3 parts gravel 2 parts sand 1 part cement just enough water to make a paste

Q: The chimney is deteriorating due to water getting in the cement block.: Do as the previous answer suggests by adding another flue tile. In order to be up to code you must use refractory cement to join the tiles. Also chip out a little)about half an inch from the flue and fill with a high heat pure silicone. As the flue tile heats up it will expand and then contract when it cools down. The silicone will keep the top from cracking and allowing moisture in. We have been chimney sweeps for 36 years and see crowns always spider cracking from the corner due to expansion. This prevents this from happening and allowing water in. Water will destroy a chimney over time It gets in through the cracks and makes its way to the smoke shelf picking up creosote and fly ash. The mixture turns to a lye like acid and eats the mortar holding the bricks together and soon causes the chimney to fail.

Q: How long before i can dive on newly poored cement?: What made your new cement poor? Did someone take away all of its money? Poor cement is a sad situation. Ya know, your cement is not unique. There are many poor people in the country, too. Maybe some of those poor people should open a lemonade stand where they can POUR some lemonade to make some money. But, I'd bet that those POOR people are smarter than a 2nd grader and know the difference between POOR and POUR. You clearly don't as you had only 8 words that were more than two letters and you couldn't proof read well enough to make the change. Poor you. PLUS ... you'd actually be STUPID enough to dive onto cement? Well, if the cement was recently POURED, you'll need to wait about 24 hours and then the cement will be hard enough to, if you hit head first, kill you. So ... make a decision about your level of injury. But, based on your ignorance about such a simple word as poor/pour, you'll likely dive onto the cement face/head first.

Q: All I can find is on Wikipedia, but I need more than that!I would be really grateful!!Thank you!: You are looking at lime based mortar and concrete (opus siginum to the Romans). I have used ordinary builders lime, dry in bags, and mixed it as you would with cement 5:1, and let it rest for around 24 hours before use. the great thing about lime based mortar is that when it begins to go hard, you can add more water and mix it again without loss of strength as would be the case with O.P.C. It does take a long time to set, weeks if the weather is cold and wet but the resulting mortar is very good for stone and soft brick as it will allow the structure to move and settle, also when frost freezes the water in the wall, it is the lime mortar that is blown out, not the stone or brick.

Q: I am installing a 3-foot wooden picket fence.: use cement, dig hole,, put post in, put cement in, put water in, make sure its level done

Q: We are creating cement test samples in construction materials class and our group is to use a .55 water/cement ratio. Our test cylinder is 4quot; diameter by 8quot; height. I know that this is 0.058 ft?. I am having trouble trying to figure out a formula that i can figure out how much water/cement/aggregate that i should put in this cylinder in order to make 0.058 ft?.: First you need to determine the specific density of the cement usually 3100kg/m3. The aggregate and sand will be about 2600kg/m3. Next determine the ratio of cement to fine aggregate (sand) to coarse aggregate. A fairly low strength concrete would have a ratio by weight of 1:2:4. The density of the finished concrete will be about 2400kg/m3. So start with 100kg of OPC (Ordinary Portland Cement) then fine aggregate is 200kg and coarse aggregate is 400kg. The water is 55kg (0.55 w/c ratio). Add up total weight and obtain volume by using overall density of mixture (2600kg/m3). This volume is called the yield. By using the ratio of the quantity that you require against the yield using 100kg of OPC you can calculate the amount of OPC, sand, Aggregate and water that you need.
