While environmental engineering does have merit as one choice within the broad classification of civil engineering, I believe your background in chemistry should be exploited. I would recommend you consider concentrating your graduate studies on matters related to WATER. Developing new and...

If you design the concrete mix to attain a compressive strength of 5000 psi in 28 days it will probably achieve a flexual strength of approx. 600 psi in 28 days. The local aggregates are a major factor in this relationship and cylinder tesitng must be called for to substansiate this possible...

Assuming that this terminal is in a geographic area that has frequent to periodic rain your design has flaws. Water will seep into the base course through the sand joints and will lead to a loss of uniform support for indivigual pavers. Also, lime stabilization of a "gravel base" is...

Was the cincrete slab pre-stressed in both directions?? Also, where did the crack occur? was it parallel to a line of prestreessing cable??

Developing a 'simple' impact testing mechanism for concrete may not be that simple. A value of toughness of concrete is sometimes evaluated by determining the impact resistance of the concrete using a device that directs steel balls or BB's in the surface of the concrete. This is an imprecise...
