Concrete mixing is a basic skill that every DIY fan needs to know. Concrete is one of the most common and inexpensive building materials on the planet, consisting mainly of sand, gravel and cement.
Concrete mixing is similar to baking, so it is best to follow a particular recipe to achieve consistent results. There are many different concrete mixes for different applications depending on the strength, feasibility and applicability of the concrete.
Concrete mixing for professionals is very science, but for the average backyard fan, getting to know the foundation of the concrete is enough to get you started.
Concrete mixing involves mixing ingredients such as sand and gravel as well as cement and water catalysts to initiate the chemical bonding process of the ingredients. Concrete mixing is a function of the proportions where the amount of cement used is measured for the amount of cement used.
The most common concrete mix used worldwide is the 3-2-1 blend, which uses three-part gravel, two-piece sand and one-piece cement. Water is added to the idea of using as little water as possible to make it concrete for what you need. The viscosity of the concrete is measured by "sliding", which refers to a specific test where the cone placed on the concrete takes its shape when the cone is removed or measured in millimeters. Zero recessed concrete is very rigid and dry and bent to retain its shape, where a 6-inch or more slip concrete would be extremely wet and not inclined to shape.
The 3-2-1 mixture is widely used because it can fill large areas with relatively cheap concrete. You may only use sand and cement, not gravel to create mortar. In the 3-2-1 mixture, the gravel serves as a filler that occupies a large space while retaining relatively high total strength. The disadvantage of the 3-2-1 mixture is that the larger gravel aggregate often floats on the surface and is not suitable for thin or detailed concrete surfaces.
The most suitable blend for a DIY fan to remember and use a simple 3: 1 mortar mixture. Using three-piece sand and one-piece mortar, you can create the most powerful concrete and concrete that is easy to install and detailed, with patterns, templates or stamps. If you do not use the gravel, the mortar will have a more consistent consistency, but will be less than the gravel concrete. If a very large amount of concrete is drilled, the gravel may prove to be cost-effective, but for most DIY projects the mortar mixture is 3: 1.
The sand to be used for the 3: 1 mortar mixture must be sharp sand or masonry sand or abrasive sand. Any place you buy in sand will use a different term, so it can be confusing when shopping. All we need to remember is to avoid sand. Sand is sand that has been washed and sterilized (this is fine) and then softened to the edges of each sand grain (this is bad).
The sharp edges of the sand help to better match the concrete mix than the rounded edges of the sanded sand. Ideally, you want to find sand in the landscape supply stores that sell in the yard of the cube. With a strong trailer you can pick up as much sand as you can, and the quality of the sand that is needed to make the cement will be very high.
Requests for DIY fans to use a 3: 1 mortar mixture are enormous. With a simple blend of sand, cement and water, everything can be fixed by breaking the broken stairs and stairs, wires, terraces, decks, lakes, waterfalls, artificial rocks, sculptures and much more.
Start with the small concrete projects to feel better and understand how to work with concrete. Because concrete is so popular around the world and highly advanced science, you will never run out of interesting, concrete applications to get to know or try. The most affordable building material available on the planet and easily accessible everywhere – learning basic mixing of basic concrete recipes is a basic DIY project.
