In... 1983, with Joseph Sawyer as head of Lone Star's research laboratory... I started to develop early high-strength geopolymeric binders and cements based on based on both geopolymeric and hydraulic cement chemistries. Within one month Lone Star Industries Inc. formed the development company, PYRAMENT... exclusively dedicated to... this new class of cement. ...It was discovered that the addition of ground blast furnace slag, which is a latent hydraulic cementitious product, to the poly(sialate) type of geopolymer, accelerates the setting time and... improves compressive and flexural strength. The first Davidovits and Sawyer patent was filed in... 1984... The corresponding European patent... in 1985... and these... disclose our preliminary finding...of 1983. Geopolymer cements are acid-resistant cementitious materials with zeolitic properties that can be applied to long-term containment of hazardous and toxic wastes.

[W]e have two civilizations, one in the north that flourished during the Old Kingdom, god , agglomerated stone, [and] that in the south that flourished under the New Kingdom, god , and carved stone.

How should we consider geopolymers? ...a new material, a new binder or a new cement for concrete? Geopolymers are all of these.

The blocks consist of... ninety to ninety-five percent limestone rubble and five to ten percent cement. ...imitations of natural limestone, made in the age-old tradition of alchemical stonemaking. No stone cutting or heavy hauling was ever required...

... form[s]... one of the major areas of materials science. ...Inorganic chemistry concerns basic molecules such as s, metals, s, and minerals. ...[M]ost of the raw materials for geopolymer synthesis are rock-forming minerals. ...There are numerous reasons for being interested in mineral polymers, more specifically in geopolymers. One is to get fire and heat properties that cannot be covered by organic materials. Another is the bridge... between polymer science and ceramics.

When the Egyptian alchemists developed glassmaking during the New Kingdom, it was to carry on the old religious tradition of making synthetic stones.

Geopolymeric products range from advanced materials to simple, yet highly sophisticated cements. The geopolymeric cements are made with inorganic chemical reactions in which alumina and silica materials are integrated to form synthetic s, secondary rock-forming minerals.

They turned back to mud because mud bricks is also a replica of incarnation, in the materials that belong to the Khnum divinity.

[F]or god in the creation, he carves mankind and the other gods in his body, the mountain. The creation is the divine incarnation in carved stone.
