This experimental investigation aims at developing one-part mix alkali activated materials using only waste materials.
Table 2 Comparison of performance of construction process Curing time [min] Working time efficiency Foam accuracy Required accuracy of ejection Material loss One-part foam 60 Low Low Low High Two-part foam 10-15 High High High Low.
The primary reason for this was the lack of reaction between the foam and the atmosphere, since one-part foam is a moisture-cured material.
From the results of the experiments, the construction process by the one-part foam type robot uses more material and takes longer, mainly because of the curing process and waiting time for curing (1 h).
In the USA, Nordson Corp has acquired Sealant Equipment & Engineering Inc, a company based in Plymouth, Michigan, that engineers and manufactures meter, mix and dispense equipment and valves which apply one-part, two-part and three-part adhesive, sealant and lubricating materials.
The compressive strength of the material was ∼30 MPa, i.e. significantly higher than for comparable one-part geopolymers.
The plant material was dried, homogenized and a decoct was produced by boiling one part dried plant material with nine parts ethanol for 4 h.
The robot was part of a parts-retrieval system that moved material from one part of the factory to another.
In composites of archaeological material only one part may be ancient, the balance being made up to complete the object.
The problem was the interaction between a composite material on one part of the pedal and moisture which led to degradation over time.
Dr. Hugh Bollinger of N.P.I. said amaranth seemed to share with corn the characteristic of "jumping genes," or the ability to transpose pieces of genetic material from one part of a chromosome to another.
