· Cement eco-bricks are a fusion of two technologies, the 32-year-old explains. First is the additive of 50 to 100 pieces of plastic in each brick. Second is the molding process; cement eco-bricks are not exactly hollow. They are built like Lego blocks with modules on top and holes at the bottom, making them stackable and faster to pile.
A concrete ratio of 1:3:6 means that for every unit of cement you are using 3 units of sand and 6 units of aggregate. The amount of concrete blocks you can make will depend on the size unit of your mix and the size concrete blocks you intend to ma...

A concrete masonry unit (CMU) or a hollow concrete block is a standard sized rectangular hollow block made of cast concrete (e.g. Portland cement and aggregate, usually sand and fine gravel, for high-density blocks). Lower density blocks may use industrial wastes, such as fly ash or bottom ash, as an aggregate and are often called as ...
· Mortar Types and Uses. Typically used as the compound for joining masonry, stone or ceramic units together, mortar is made by combining cement, lime and sand. Mortar typically has a higher water to cement ratio when compared with concrete which allows greater workability and is required to form mortars bonding properties.
Cement to sand ratio ranges from 1 part cement to 3 to 4.5 parts sand, depending on the type of mortar being mixed and the compressive strength desired. Most mixes also require the use of lime in various proportions as a binding agent, to increase the longevity of the finished product, and to increase the workability of the mix.
Cement Sand cement Sand cement Sand 1 Bag(50kg) 3 wheelbarrows 1 Bag(50kg) 4 wheelbarrows 1 Bag(50kg) 5 wheelbarrows NOTE: sand and water should be clean add only enough water to make the mix workable mix until the entire dry mix is the same colour before adding water
the availability of the sand to be used for hollow concrete block. Comparative study was conducted by making samples of concrete hollow block from different proportion of cement and sand starting from 1:1 to 1:6. The water cement ratio was set to be 0.5 which can be predicted to be best in workability (from 0.4 to 0.6).
· More water, cement or sand can be added if the mixture is too wet or dry. Below is an example of a sand to cement mix ratio recommendation from a cement manufacturer. Concrete - 1 part cement, 2 parts concreting sand and 3 parts 20 millimeter aggregate. Mortar - 1 part cement, 4 to 5 parts building sand.
· Step 2: Calculate the volume of the 35 blocks. If the volume of 1 block is 0.0143, the volume of 35 blocks = (0.0143 × 35) = 0.502 m 3. Step 3: Calculate the volume sand required for the 35 blocks. The volume of 1 bag of cement is 34.72 litres = 0.03472m 3. This is obtained by knowing that the mass of 1 bag of cement = 50kg, and the density ...
· Summary. Considering everything, filling your cinder blocks isn''t exactly necessary, but it is completely safe, assuming you don''t add dirt in it. Filling cinder blocks can help you make the structure sturdier or improve insulation, while a mix of gravel and sand can actually help you achieve both.

The basic mixture for mortar will depend on the individual who is doing the work. Most masons use a mixture of three parts sand to one part cement, or four parts sand to one part cement. It is rare for any mason to go beyond four parts because the mixture can be too sandy and lacks sufficient binder to harden into a mortar phase.
