51.	From the below figure, what is C here?(a) Grave(b) Sand stone(c) Quartz(d) GraniteThe question was posed to me in homework.I'm obligated to ask this question of Factors Affecting Shrinkage in portion Elasticity, Creep and Shrinkage of Concrete Technology
Answer» Correct option is (C) Quartz Easy explanation: AGGREGATES PLAYS an important role in the shrinkage properties of CONCRETE. ACCORDING to option, C is Quartz.

52.	How many types of shrinkages, caused due to cooling and carbonation?(a) 1(b) 2(c) 3(d) 4The question was asked during an online interview.This is a very interesting question from Shrinkage topic in division Elasticity, Creep and Shrinkage of Concrete Technology
Answer» RIGHT OPTION is (b) 2 Best explanation: There are 2 types of shrinkage which are caused DUE to cooling and carbonation.

53.	Creep is _________ to the strength of concrete.(a) Equal(b) Similar(c) Directly proportional(d) Inversely proportionalI have been asked this question during an interview.The above asked question is from Factors Affecting Creep and Elasticity in division Elasticity, Creep and Shrinkage of Concrete Technology
Answer» Right answer is (d) Inversely PROPORTIONAL To elaborate: Creep increases with INCREASE in water/cement ratio. In other WORDS, it can also be said that creep is inversely proportional to the STRENGTH of CONCRETE.

54.	When concrete is loaded it experiences a large strain upon loading known as _____________(a) Differential elastic strain(b) Instantaneous elastic strain(c) Differential inelastic strain(d) Instantaneous inelastic strainThis question was addressed to me in final exam.I would like to ask this question from Creep in division Elasticity, Creep and Shrinkage of Concrete Technology
Answer» RIGHT answer is (B) Instantaneous elastic strain The explanation is: When concrete is loaded it EXPERIENCES a large strain upon loading known as the instantaneous elastic strain.

55.	Concrete exhibits initial elastic strain which depends on __________(a) Magnitude of applied stress(b) Rate of applied stress(c) Magnitude and rate of applied stress(d) Elastic modulusThis question was posed to me in an interview for job.The question is from Creep topic in portion Elasticity, Creep and Shrinkage of Concrete Technology
Answer» CORRECT choice is (c) Magnitude and rate of APPLIED STRESS Explanation: Concrete exhibits initial ELASTIC strain which depends on the magnitude and rate of applied stress.

56.	The grain density of the clay powders was measured using _______(a) Hydrostatic pressure(b) Cylindrical cavity(c) Pycnometer(d) Helium porosimeterI got this question in examination.I need to ask this question from Elastic Properties of Aggregates in portion Elasticity, Creep and Shrinkage of Concrete Technology
Answer» The CORRECT option is (c) PYCNOMETER For EXPLANATION I would say: The GRAIN density of the clay powders was measured using a pycnometer.

57.	If the creep effect is considered at a given load, the modulus determined is referred to as ______(a) Short term modulus of elasticity(b) Elasticity(c) Long term modulus of elasticity(d) Creep effectThis question was addressed to me in an online interview.This interesting question is from Creep in section Elasticity, Creep and Shrinkage of Concrete Technology
Answer» The correct answer is (C) LONG term modulus of elasticity Easiest explanation: If CREEP effect is considered at a GIVEN LOAD, the modulus determined is referred to as long term modulus of elasticity.
