Concrete blocks are not complicated to make. With the right mix of ingredients, you can make them at home and save a significant amount of money on your construction budget. Generally, there are two types of concrete blocks: you can choose to make hollow blocks or solid ones, depending on your preference.
If you’re an entrepreneur, learn how to make quality, but cost-effective concrete blocks on https://www.envirocon.co.nz/ and start selling them to customers. Whether you want to make concrete blocks for your use or sale, you need to standardize the size. You should also ensure that the quality of the blocks is consistently high, especially if you’re producing them for sale.
Even so, there are several things you need to do to produce concrete blocks that’ll fetch a high price in the market. Below are the things you should do to create the best mix for concrete blocks that give you a higher selling revenue:
Ensure Building Materials Are Not Contaminated
To make concrete blocks, you’ll need to source and store the aggregates. These are the raw materials you need to create your blocks, specifically the gravel, crushed stone, and sand. In addition to the aggregates, you’ll need cement.
The way you store these materials will determine the quality of the concrete blocks you produce as well as their market price. Moisture can contaminate or even damage your aggregates and cement, compromising the quality of your blocks.
To ensure that the aggregates are not contaminated, have a flat land that has enough space to store your block building materials, equipment, and the finished concrete blocks. Avoid storing the cement or the aggregates outside, under the trees, or on bare ground. Doing this exposes them to moisture that can cause damages or contaminate your materials.
Instead, identify dry areas to store your materials. Consider keeping your cement bags in a dry room. Store the cement and the aggregates separately until you’re ready to mix them up. Additionally, to cure them, store your concrete blocks in a separate space, particularly on a flat, concrete slab. It’s advisable to space 200 blocks out on a 50 square meters of space.
Invest In The Right Equipment
To create concrete blocks that bring higher selling revenues to your construction company, you’ll need a molding machine and several other general-purpose tools. For a molding machine, you’ll need an egg-layer molding machine that molds block on a concrete slab. You’ll also need the stationary mold to make the machine that creates one block at a go on the pallet.
Depending on the amount of concrete needed, consider getting a concrete mixer to ease the mixing process. Alternatively, you can mix the concrete by hand if the amount you need is relatively low. This is quite an amount of hard work, but it’ll save you some cash.
Always mix your concrete on a slab, and not directly on the earth’s surface. This prevents contamination of the concrete by soil. To mix the semi-dry concrete that you need to make the concrete blocks, get a pan or concrete mixer. Other pieces of equipment that you’ll need to get the job done are shovels, wheelbarrows, plastic sheeting, and hosepipes.
Use The Right Mix Of Aggregates And Cement
For your concrete blocks to fetch a high selling price in the market, their strength class should be 42, 5N, or more to cure fast. The aggregates in the concrete blocks should be stones and sand. If you want to make hollow bricks, the stones shouldn’t surpass the 10 mm size, while the sand should be 5mm in size.
To make solid blocks, you’ll need stones that measure 13mm. You can create blocks using coarse sand alone or use a mix of the aggregates. Consider testing the block strengths using a cement to aggregate ratios of 1:6, 1:8, and 1:10. With each ration, mix the concrete with water before molding the mix, allowing you to create the blocks. This enables you to get the perfect mix for the market. Ideally, the heavier your molded brick is, the higher the quality.
You can test how strong your concrete blocks are by knocking dried up pieces together. If they produce a ringing sound, the blocks are strong. A hollow thud means your blocks are still weak.
Making quality concrete blocks is the best way to boost your sales revenue. To create high-quality blocks, you need to use the right mix of cement and aggregation, maintain the integrity of the block-making materials, and have the necessary equipment for mixing and molding block making materials.
If you want to create the best mix for concrete blocks, follow the advice presented above.
