Why Portland cement is called hydraulic cement?
Portland Cement is classified as "hydraulic" cement because it cures or solidifies due to its chemical exchange with water, stemming from the building material's ability capability to set under water. In the well industry Portland Cement can be placed or pumped into voids at thousands of feet in depth. As long as the mixture is released or pumped without significant breakdown of the mixture due to water flow the cement will cure just as well we see during ground level applications.
What surface can you install tile on?
Tile is best placed onto cement or cement boards. With that stated Custom Building Products, one the biggest makers of tile thinsets and cement boards says it is allowable, although not preferred to install on CDX plywood but your total floor must be 1 1/4" with all subfloors. Back splashes in areas that are not exposed to steam or water can install onto plaster walls.
How do you you pump a balanced cement plug?
Balanced cement plug is pumped through drill string or open-ended tubing. 'Balanced Cement Plug' means that the top of cement outside the drillstring/ tubing will be the same height as the top of cement inside the drillstring at the end of pumping. The drillstring/ tubing is then slowly pulled from the wet cement, allowing the cement inside the string to fill the centre of the plug. There are lots of refinements in this method with open hole cement retainers or high viscosity 'cushions' often placed below cement. In vertical hole, most balanced plugs are successful. In extended reach wells, failure rates can be high with cement slumping and mixing with synthetic based muds. A typical checklist to improve cement plug success in extended reach wells would have: 1. Always use a tailpipe. This reduces the disruption to the plug caused by removal of the drillstring. 2. Clean up the hole thoroughly before pumping cement. Cement is an excellent hole cleaner. Many 'flash set' events reported are really packoffs caused by cement picking up a cuttings dune. 3. Put a diverter tool with BIG holes on the bottom of the tailpipe. This directs fluids up the hole during cementing 4. Use a scavenger spacer in front of the cement job to convert the formation from oil wet to water wet. 5. Slow down pumping to 1 BPM while displacing cement into open hole. This reduces mixing of cement and mud. 6. Put a cushion below the cement plug. A cement retainer is best. If a viscous cushion is spotted, weight the cushion to 1 ppg below the cement weight. 7. Gravity is NOT on your side. Cement can stay inside the tail pipe as you pull it from the plug. Pump the volume of cement inside the tailpipe as you pull the tailpipe from the plug. 8. Circulate clean the long way with the bottom of the tailpipe at the planned cement plug top.
How can damage from strip mines be repaired?
It actually takes place on an ongoing basis in the US. When a mine is closed, there are funds that have been set aside for restoration of the mined area. Land is contoured, topsoil placed where it is needed, and lands planted with vegetation that will grow in that area.
What are column footings?
From the ancient days itself, the column has been used as a re-enforcement for many of the infrastructures and has also been recognized as a work of art representing a sense of style and grandeur. If you are looking to build one, here are the tips on to get started : Required Tools : Masonry brush gloves Masonry brush Cement Rubber cement Water Shovel 5 gallon pail Wood (including 2*4 ply) Here are the instructions to build : Firstly before you begin, it is important you have a design of how your column footing should look. So design one. Get a shovel and start digging the hole where the column footing must be placed. then dig an area around the column hole where the footing will be placed. The hole must be 12 inches deep and 23 inches wider. Make a frame for each side of the foot using a 2*4 inch board. Once done, cut the frame to fasten them together. Use a custom made 'form' to fasten the plywood and attach the lip of the form to the top of the plywood. Start coating the inside part of the frame with quick drying rubber cement. Now use the shovel to mix two batches of cement with and without the gravel. Take smooth cement using the pail and full the frame below the edge of the outside walls. Now lay another layer of cement which is 4 inches deep into the 12 inches hole for the column. Once you have mixed the cement, you will place the column footing in it.Then you should allow it to dry.Next you should remove the frame and form from the hardened cement and peel the rubber. Then allow the column to air dry. Use the smooth cement to fill the empty gaps. Get masonry brush and put on masonry gloves to brush the final product so everything is smooth. Hope this helps.

What is hair restoration surgery?
A thin strip of donor hair is harvested from the donor area which is the region of hair on the back of the head in which the hair is genetically programmed not to fall out. These hairs are permanent. The donor strip is then placed under a microscope designed specifically for hair restoration surgery and the strip is then dissected into microscopic grafts of individual follicular units, of one to four hairs. This all important step in hair restoration surgery must be precise in order to gain the best yield from your donor area. These precious grafts are placed in a cold, tissue storage and kept as such until they are meticulously placed in the recipient sites.

How is cement stored on a construction site?
Dry cement in bags is stored in a dry place protected from the weather. For large construction sites this is usually a secure storage area. If you are talking about mixed cement (wet) or concrete, then it is not stored on a construction site. It is mixed off-site and carried to the site in large "cement mixer" trucks. The it is placed (or poured) prior to the initial setting time specified by the concrete manufacturer.
Use Hair Restoration Formulas Carefully?
One of the most popular forms of hair restoration is the use of Minoxidil. This formula can be found in various over the counter and prescription hair restoration treatments and medicines. Originally used to regulate blood pressure, Minoxidil actually tends to grow hair wherever it is placed. If using this substance for hair restoration, be careful when applying the scalp medication, as poorly applied minoxidil can result in an uneven and false looking hairline.
