• Abstract:

  The object of the investigation was primarily to ascertain the fire retardant properties of Straub blocks as employed in the construction of walls. The tests which afforded information relating to fire resistance of the material were supplemented by other tests and examinations intended to show the composition of the material and to afford data for purposes of identification; the compressive strength of the blocks; the effects of saturation with water and subsequent freezing and thawing; the practicability of handling and shipping the blocks; the procedure to be followed in constructing a wall; the effect of the application of a hose stream toa specimen wall that had been exposed to fire; and the effect of a falling beam or column upon the same specimen wall.
