If there are no sandpits from which it can be dug, then we must sift it out from river beds or from gravel or even from the sea beach. This kind however has these defects when used in masonry: it dries slowly... and such a wall cannot carry vaultings. Furthermore, when sea-sand is used in walls and these are coated with stucco, a salty efflorescence is given out which spoils the surface.
Vitruvius
Friends, wives and husbands, sons and daughters, dead
Of plague, famine, and arrows: and the houses
Battered unsafe by cannonades of stone
Hurled in by the Assyrians: the town-walls
Crumbling out of their masonry into mounds
Of foolish earth, so smitten by the rams:
The hunger-pangs, the thirst like swallowed lime
Forcing them gulp green water maggot-quick
That lurks in corners of dried cisterns: yea,
Murders done for a drink of blood, and flesh
Sodden of infants: and no hope alive
Of rescue from this heat of prisoning anguish
Until Assyrian swords drown it in death.

The concrete shell of this stove would surely crack if its strength were not reinforced with steel rod, wire fabric, or barbed wire. The latter is our choice. We laid continuous strands of barbed wire between the rows of slip form masonry. The thermal expansion rate of concrete is the same as steel up to a temperature comparable to boiling water... Beyond that, steel expands at a faster rate than concrete. At a temperature of about 500 degrees F., the bond between the concrete and steel is destroyed... The type of aggregate in the mix is primarily responsible for this kind of failure.

Om or Aum (Sk.). A mystic syllable, the most solemn of all words in India. It is "an invocation, a benediction, an affirmation and a promise and it is so sacred, as to be indeed the word at low breath of occult, primitive masonry. No one must be near when the syllable is pronounced for a purpose. This word is usually placed at the beginning of sacred Scriptures, and is prefixed to prayers. It is a compound of three letters a,u,m, which, in the popular belief, are typical of the three Vedas, also of three gods-A (Agni) V (Varuna) and M (Maruts) or Fire, Water and Air. In esoteric philosophy these are the three sacred fires, or the "triple fire”in the Universe and Man, besides many other things...
