I'm looking at a Cement Grouting specification for curtain grouting on new dam construction. It mentions having set control of Type I/II Ordinary Portland Cement slurry grout down to a 10-seconds. What admixture would do this?
Unconfined compressive strength testing of 2-inch cubes has been specified to follow ASTM C 942. What is the primary difference, if any, than testing to ASTM C 109? The question is in terms of curing, loading and breaking, nothing to do with casting and/or preparation of the grout cube.
Will the age or stage of the hydration process of a cement mixed soilcrete have an influence on permeability when testing in a triaxial apparatus per ASTM D 5084?
After a soil-cement mix has cured to the state of being able to be cored, say 4 or 5 days, will there be a permeability difference...
Is there a simple table or chart showing typical unconfined compressive strengths for a neat cement slurry grout mixed and cured at different water to cement ratios? Quite simply, Type I/II portland cement mixed at water to cement ratio of 1.39, what are the 7, 14 and 28 day unconfined...
Can anyone direct me to a literature source regarding design of Soil Fracture Grouting aka. Compensation Grouting. This will be employeed to remediate lost ground from tunneling within granular soils.
I need to determine spacing between injection points (primary/secondary), injection pressures...
Does anybody know of a (electric) tankless water heater that is 110/120 volt 15-amp? All I need is something very small. I have 15-amp service available and would like to avoid rewiring for 30-amp as most 120 volt heaters seem to be.
I have a Yamaha WR426F with a fourcycle engine with a 12.5:1 compression ratio. Yamaha specs that the minimum octane rating is 95 and must be an unleaded gas. Most all pump gas within this area does not exceed 91 and does not work well at all when used with an octane boost additive. Race fuel is...
