Crack Detection

Concrete materials are meant for supporting structures, building foundations and they act as several load-bearing structures. Over time, due to environmental conditions, and based on the constituent materials used, concrete materials are subjected to a great degree of distress. Corrosion of the reinforcement bars due to chemical influences, uneven base, earthquake, drying shrinkages, and alkali-aggregate reactions are some of the reasons for concrete distress.

Question

Concrete is required for walls of a building that will be Moderately exposed to
freezing and thawing. The cross section of a wall is 300 x 1500 mm. The smallest
spacing between reinforcing steel is 50 mm. The specified compressive strength of
concrete at 28 days is 30 MPa and a slump of 40 mm. Portland cement type I is used
with specific gravity of 3.12, maximum size of aggregate 27 mm and fineness
modulus of fine aggregate is 2.4, absorption capacity and moisture content of fine
aggregate are of 0.92%, and 1.95% respectively. The dry-rodded unit weight of coarse
aggregate is 1820 kg/m³, absorption capacity and moisture content of coarse
aggregate are of 0.75%, and 1.85% respectively. Both aggregates have a bulk specific
gravity (SSD) of (2.45). The aggregates conform to the ASTM C33-84 requirements
for grading. Estimate the quantity of (cement, fine aggregate, coarse aggregate and
water) for 1m³ concrete.

The strength of cement is determined by a number of factors.
The flexural strength (fr) of concrete measured from the bending test is always higher than the direct tensile strength (ft). In reality, the stress in the cracked part of the concrete is lower than ft. Also, failure may occur on the compressive side. Assuming NO tension softening (i.e., the stress in the cracked part stays at ft) and infinite compressive strength (i.e., compressive failure will never occur), draw the stress distribution over the depth of the beam at ultimate failure when the curvature of the section is approaching infinity. With this stress distribution, show that the upper bound of fr/ft is equal to 3. (Hint: On rotating the section, because the compressive stress can increase well beyond ft, the neutral axis will continue to shift upwards.)
