The Basics of Block and Brick Making
1)Input Materials for Cement Blocks and Bricks
1.1)Aggregate
Aggregate is the stone, sand and ash you want to vibrate and compact down and bind together with the cement. A good aggregate is an aggregate that is free from chemicals, clay and organic material. A good aggregate will bond well with the cement paste and not react with it.
As a rule of thumb, the denser your finished brick or block the stronger the brick or block will be. You must choose your aggregates according to your needs.
To achieve a dense block with an aggregate that can be vibrated and compacted down easily you need to have an aggregate with evenly graded particles ranging from fine dust up to larger stone of around 9mm. Blending different aggregates/graded materials often produces the best results.
See Appendix A . Aggregates.
1.2) Cement
Vibraform only recommends 42.5 MPA (or higher) ordinary Portland cement (OPC). If this grade is not available a higher percent of 32.5 MPA must be used in the product mix.
Cement is your most costly material and by doing trials with different aggregates you will be able to minimize on cement content and so decrease your costs.
Cement should always be stored in dry place, off the floor and should be used within three months of the date of manufacture.
Never use cement that has lumps in it and only use cement from a well-known, quality brand.
Cement sets when mixed with water by way of a complex series of hydration chemical reactions. The different constituents slowly hydrate and crystallise while the interlocking of their crystals gives the cement its strength after the initial setting.
Immersion in warm water will speed up the setting. The time it takes for cement to set varies; and can take anywhere from twenty minutes for initial set to twentyfour hours, or more, for final set.
1.3) Water
Only clean, clear potable water should be used in the manufacture of the blocks and bricks.
Any organic material in water will prevent the cement from setting. Chemicals and impurities could also affect the strength of the end product.
Never use, salty or brak water. It is advisable to get your water tested for impurities
Brak water/ contaminated water

Mixes are subject to change if using higher M PA cements or with variations in types of materials i.e. aggregates used
