embodiments the material is pressed using a force of between about 200 and 2000 psi it is to be appreciated that the cementitious material is substantially fireproof much as conventional cement is it is also to be appreciated that the cementitious material has properties that are not possessed by conventional cement for example the cementitious material is sawable can be sawed with a conventional saw and nailable can be nailed with conventional nails much as wood is moreover screws can be used without the anchors required by conventional concrete reference will now be made to specific examples using the processes described above it is to be understood that the examples are provided to more completely describe preferred embodiments and that no limitation to the scope of the invention is intended thereby a 4 u2033 by 4 u2033 by 1 u00bd u2033 block is prepared as follows first soak u00bd lb of u201c dry u201d wood chips in water overnight or until substantially saturated then drain the excess water from the mixture in a separate container combine 1 lb dry portland cement with u00bd lb water mix to make a cement slurry add the wet fibers to the cement slurry and mix thoroughly until all the particles of the fiber are coated with the slurry the mixture will feel sticky and you will not feel any grain while the fiber cement slurry is mixing combine u00bc lb monomagnesium phosphate u201c mop u201d with u215b lb water mix gently for 20 30 minutes or.
