Q.1 Concrete is a composite material. From microscopic point of
view, it can be considered
as a three-phase composite with aggregate, cement paste and
interface zone between
these two components.
1. For concrete with 28-day compressive strength of 35 Mpa
(5076psi) made with
ordinary Portland cement and crushed granite aggregate, which phase
of the
concrete is generally the weakest?
2. If the granite aggregate for the concrete mentioned in (i) is
replaced by lightweight
aggregate. How would this affect the strength of concrete?
3. If we would like to increase the strength further, what approach
shall we take?
Note: Explain in detail answer quetion.

| Shiancoe | Mar. 1 | 3,600 | 551 | ||
| Ward | Nov. 16 | 8,400 | 1,814 | ||
Required:
1. Calculate the amounts to be reported on each employee's Wage and Tax Statement (Form W-2). Enter amounts to the nearest cent if required. Enter all amounts as positive numbers.
| Employee | Gross Earnings | Federal Income Tax Withheld | Social Security Tax Withheld | Medicare Tax Withheld | ||||
