Assessment of hydrated lime
and fumed silica were conducted in the same manner as the diatomaceous earth study, except as follows: the paired-choice feeding deterrent assessments using the dusting and sprinkling methods were conducted with 20 slugs in individual containers in each case.
The cone calorimeter test was performed on the base binder (BA), 40 wt.% hydrated lime
modified binder (HL), 40 wt.% limestone modified binder (LS), and 40 wt.% magnesium hydroxide modified binder (MH), simulating the asphalt combustion process under a fire condition with 50kW x [m.sup.-2] radiation intensity.
Do wear goggles and hand protection when handling hydrated lime
as it can be an irritant to some people.

By contrast, the possible disadvantages are: * Needs to be mixed into, and maintained, in a slurry in water state, as is the case with hydrated lime
. * Slow reaction rate -- can be increased by more vigorous agitation and/or by a |topping up' technique.
Bill Ayers, president and CEO of Mississippi Lime, said, "This acquisition is consistent with our continued mission to be the leading supplier of hydrated lime
products and services in North America.
The expansion will focus on producing hydrated lime
for acid gas control in the greater Cincinnati area.
The material was then inspected to determine which soil stabilizer to use - hydrated lime
, portland cement, or asphalt emulsion.
announced the expansion of hydrated lime
production capacity at its Ste.
