1. The strength of concrete prepared, cured & tested under specified conditions at a given age isdepending on some parameters: - List these parameters2. Discuss the main methods used for concrete curing and their effects on strength.3. Discuss the relationship between compaction of fresh concrete and pores in hardened concrete.4. What is the effects of pores on hardened concrete properties, especially strengths anddurability?5. Why extra water is harmful to fresh concrete and what is its effects on concrete at hardenedstate?6. Discuss the different types of volume change in concrete at early and long-term ages.7. The third-point loading flexure strength test was performed on a concrete beam having a crosssection of 150 mm by 150 mm and a span of 450 mm. If the load at failure was 35.7 kN,calculate the flexural strength of this concrete.8. A center-point loading flexural test was performed on a concrete beam having a size of100x100x500 mm. The beam is sitting on two supports located at 25 mm from each edge ofbeam. If the failure load was 17.5 kN, find the flexural strength.9. Considering the two tests of flexure, 3-points and 4-points, which one is more suitable forbending test and why?10. The compression strength test was performed on several samples of concrete molded in fourtypes of molds cubes of 0.100 mx0.100 m x0.100 m and of 0.150 mx0.150 m x 0.150 m, andcylinders having a cross section of d=100 mm by H=200 mm and d=150 mm by H=300 mm,respectively. If the weight of the samples and the loads at failure are as given in the Table. Bothcubes and cylinder samples are cast from the same concrete batch under the same conditionsand subjected to the same curing method.

A concrete test cylinder with a cross-sectional area of 28.3 in squared is to be tested in axial compression. Before loading two marks are scribed on the cylinder precisely 8 in apart (as shown in the figure below) when the load is 40,000 lb the marks are measured and found to be 7.997 in apart determine the E value for this concrete. Assume an approximately linear relationship between stress and strain.
True or false: Generally speaking, concrete will be priced the same regardless of its designed strength, 4,500 psi concrete will cost the same as 3,000 psi concrete.
Which one of the following sentences is not correct? a. For many years, tensile strength has been measured in terms of the compressive strength. b. The modulus of rupture where the normal-weight concrete has an fc of 4000 psi is 474 psi. С. For lightweight concretes tensile strength depends largely on the porous aggregate. d. For normal weight concrete, the tensile strength depends primarily on the strength of bond between hardened cement paste and aggregate. 13:54
