Explain the Water to Cement ratio effect on the
Compressive Strength of Concrete Cylinders. What is the normal
range of the Water to Cement ratio utilized in a concrete mix
design?
a – List down the common testing of cement, fresh concrete,
and hardened concrete.
b – How many types of curing for concrete specimen? What are
they? Which curing method is practically required for laboratory
testing?
c – Explain why the strength of concrete is increase as
increasing of curing age?
discuss this please
1. The relationship between the fineness of cement and
the resistance to concrete compression.,
2. The maternal heat rate of five types of Portland cement.
3. The development of resistance to pure compounds paste in
cement
4, the rate of maternal heat rate, originally, types of Portland
cement
Abrams established a rule that relates the water-cement ratio to
strength of concrete. List two additional factors that have a
significant influnce on the concrete strength.
Q2. Explain does why: • The transtion zone impact more rich
cementitious mixtures than lean ones.
• Air entrainment reduce the strength of moderate to high
strength concrete yet may enhance the strength of low strength
concrete.
• ASTM cements Type I. III, and V have different impact on early
and later strength of...
-How does strength correlate with other properties of hardened
concrete?
-What is the relationship of splitting tensile strength of
concrete with its compressive strength?
-What is the significance of splitting tensile test
experiment?
-Why plywood strips are used in splitting tensile test?
Discuss why air-entrained concrete mixtures require
lower water-to-cement ratio in comparison with non-air-entrained
mixtures.
Discuss the importance of the slump test for fresh
concrete.
