Architect Jack Munro, who recently graduated from the University of Westminster in London has managed to develop of process that uses cattle blood as a binding ingredient that can be used to make bricks!
Approximately 8 gallons of blood are produced by a single cow that is slaughtered. This blood is normally thrown away and that is where Munro got the idea (while he was still a student) to use this unwanted cattle blood to facilitate the formation and solidification of bricks that could be used in construction.
He started testing various different mixtures and eventually found a formula that he was happy with. It includes the blood, anticoagulant, an antibacterial agent, sand and water.
This formula gave him a waterproof crimson brick that is hardy enough to be used as a building material. Munro’s cattle blood brick could be used in places that are scarce in resources like war-torn areas of the Middle East or Africa.
Munro’s brick could also be useful in parts of the world which suffer from water shortages because they require less water to create than a mud bricks that are traditionally used in areas like these.
He has admitted that the cattle blood bricks are not nearly as strong as the normal kind of brick that is made using clay – however he does claim that they are at least as strong as mud bricks that are frequently used in many poverty-stricken communities.
