As an engineer in charge for concrete mixing, you are requested to prepare concrete mixes for a housing construction project. Therefore, a few things need to be considered prior to the mixing process. (a) If the cube test recorded lower compressive strength than the required minimum strength stated in the drawing, suggest an immediate action need to be taken by the engineer? (b) Describe the steps to design a concrete mixture using DOE method for normal concrete. (c) Explain FIVE (5) factors that are required for determining mix design proportion.

If the cube test recorded lower compressive strength than the required minimum
strength stated in the drawing, suggest an immediate action need to be taken by
the engineer?
(b)
Describe the steps to design a concrete mixture using DOE method for normal
concrete.
(c)
Explain FIVE (5) factors that are required for determining mix design proportion.
(d)
Give your opinion on the principal properties of 'good’ concrete for construction.
