In 1980, Charles Laleman of France received a US patent (No. 4,203,674) for a technique for making concrete by mixing together cement with blood. His patent described a variety of different recipes one could use to create this blood concrete. For instance:
EXAMPLE 1
A light colloidal concrete is prepared by using:
a commercially available cement (cement CPA 400), a silico-calcareous sand graded no higher than 0.8 mm (the cement/sand mass ratio being equal to 1), whole blood powder of animal origin, a colloid, and mixing water in variable proportions.
The various constituents are mixed by means of a mixer working between 100 and 600 r.p.m.
