QUEST$$ON $1$ TABLE $1$ and TABLE $2///////////$

Part $1.$ Discussion of Lab#$02$ Results

Introduction: Provide a short description of the scope of the study and information on aggregate. The Introduction section should be written in your own words, and not copied from the laboratory manual. The Introduction should first state the objective of the experiment conducted in the laboratory and then give any necessary background information, such as what theories the experiment was intended to test, validate, or exemplify. Remember to use citations for any

Use $12-$point type for text, captions, and author contact information. For typing within figures or tables, the $12-$point size is preferred. Please use the text font Times Roman. Italics and bold formats may be used; we recommend sticking to one "family" of typefaces. The paper must be written in the best possible technical and grammatical English Questions

Tahle $2.$ Flow Table Results

$2.$ Discuss the impact of the addition of superplasticizer and AEA on the workability of cement mortar.

$x$

$3.$ Discuss the impact of adding silica fume, slag and fly ash on the workability of cement Dortar.

$4.$ What would you expect about the $28-$day compressive strengths of these cemen mortars? Discuss the influence of w$/$c compressive strength of cement mortar.

Part $2.$ Design the concrete mix according to the following conditions.

Briefly show all the assumptions, selection, and calculations. Prepare a final table including material proportions for $1m^3$ and $7m^3$

Design Environment

Reinforced concrete wall exposed to seawater

No admixture will be used.

Required average $28-$day compressive strength $=30$MPa

Use $30\%$ Slag replacement in the mix design.
