It’s easy to make the sim­plest type of ce­ment your­self. In this ex­per­i­ment, we’ll pre­pare a mix­ture which you can use to make a lit­tle house, for ex­am­ple for a dog.

Safe­ty pre­cau­tions
Wear a pro­tec­tive mask, gloves and glass­es, and work in a well-ven­ti­lat­ed room.

Warn­ing! Only un­der adults su­per­vi­sion.

Reagents and equip­ment:
* build­ing lime (cal­ci­um ox­ide, 100 g);
* sand (300 g);
* wa­ter (100-150 ml);
* deep con­tain­er for mix­ing;
* trow­el;
* bricks.

Step-by-step in­struc­tions
Mix the build­ing lime with wa­ter. Grad­u­al­ly add sand and stir thor­ough­ly. We get a sim­ple ce­ment mix­ture. Ap­ply it to bricks and leave for a week. The bricks are stuck to­geth­er!

Pro­cess­es de­scrip­tion
In the re­ac­tion of cal­ci­um ox­ide with wa­ter, cal­ci­um hy­drox­ide forms.
СаО + Н₂О = Са(ОН)₂
In air, cal­ci­um hy­drox­ide re­acts with car­bon diox­ide with the for­ma­tion of durable cal­ci­um car­bon­ate, which en­velops and sticks the sand par­ti­cles to­geth­er
Са(ОН)₂ + СО₂ = СаСО₃ + Н₂О

Mixing a small sand and cement bucket mix like this by hand is not only fast, but very cheap for small DIY jobs around the house. A lot of repair jobs even for professionals involve 'knocking up' small amounts of mortar like this. This is I believe an essential life skill, like knowing how to wire a plug, or unblock a sink.

Great for small pointing jobs, pointing lead flashings, brickwork chases, walls and chimney to name but a few...

For lager jobs why not consider a builders spot mix : http://youtu.be/ehBKETtRImk

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource.

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction.

Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement. Excess free lime, for example, results in undesirable effects such as volume expansion, increased setting time or reduced strength. Several laboratory and online systems can be employed to ensure process control in each step of the cement manufacturing process, including clinker formation.

This video tutorial details the process of making a Poly 75-70 polyurethane rubber mold of a concrete stepping stone. In this example, we utilize the "poured block mold technique", which is considered to be one of the most simple mold making methods.

Although the stepping stones in this scenario can be easily replaced through options at retail stores, this mold making method is great when you have a unique stone that is not replaceable OR when you'd like to produce custom pavers from your original design (made from wood, clay, a printed model, etc.).

A full list of materials and tools used for this project can be found at the end of the video.

The Steps:
1. Select a Model [0:32]
2. Apply a Sealing Agent (Poly PVA Solution) [0:53]
3. Prepare Model and Construct Mold Box [1:24]
4. Apply Release Agent [3:33]
5. Calculate Amount of Rubber Needed for Mold [4:13]
6. Measure, Mix & Pour Mold Rubber [5:03]
7. Demold [6:29]
8. Cast Concrete [7:24]

You can use concrete paver blocks as edging for your garden beds, or to give your driveway a makeover.

In this video, I'd like to share how I make concrete paver blocks using plastic molds. Also included are tips on how to demold properly so that you can minimize your chances of damaging the resulting blocks.

The plastic molds I used come in different shapes. In the video, you'll find 3 options. Get these paver molds here: http://s.click.aliexpress.com/e/rqYgPVRi

This is a great beginner project for dipping your toes into concrete projects! I go over the steps to create basic concrete shapes and forms, and pouring. No crazy steps or perfection needed since it's just a block, so have fun and practice!

I know they are inexpensive to buy, but around here they go out of season, or you may need a shape or size they don't sell, so this can come in handy for different situations.

How to make a wooden mold for concrete pavers mobile home build.
In this video, you can see how I made a wooden mold.
-First I made a template
-Then I cut the wood for the mold
-I then assembled and screwed the mold
So the mold was ready for work I can start mixing the concrete.

I found that the best mix of cement and sand for concrete is 3 parts sand to one part cement. Water by feeling.

And so I make a patio in front of my mobile tiny house build.

To finish this tiny mobile home I need about two more months. And then we have to find another tiny mobile home project.
Stay tuned for more tiny mobile home builds!

Thanks for watching and see you in the next video!

A rubber mold for concrete statues will fail without an outside support, which is where a fiberglass mother mold (shell) is essential. The fiberglass can hold the massive weight of concrete, and it will hold the form until it hardens for demolding. It also is light and easy to use, allowing for quicker statue production. This video will give a detailed demonstration, along with tips and ideas, for creating an effective "mother mold" for creating concrete statues.

Concrete garden statues and other art, whether animals, gnomes, or seasonal figurines, enhances the garden, patio, or yard, it lasts forever, and it also makes an ideal gift. This video series will guide you through the process of making a mold for concrete statues and other art forms. You will be taught tips and methods for casting a mold of almost any item, from start to finish!

NOTE - This is the second in a set of videos on how to make concrete garden art from start to finish. Check out the channel to see the 3rd video on how to use a rubber mold with the fiberglass shell to cast and then finish a new statue for outdoors. Here is the playlist: https://www.youtube.com/playli....st?list=PLJZYCSTvzuh

Backyard Adventures with Andy Wright is a channel devoted to all-thing gardening and yard care, along with random "adventures" that include statue making, building a pizza oven (coming soon), home entertainment tips, and more.
