[amp_mcq option1=”Increase in water-cement ratio” option2=”Increase in fineness of cement” option3=”Decrease in curing time” option4=”Decrease in size of aggregate” correct=”option2″]<\/p>\n

The correct answer is: B. Increase in fineness of cement.<\/p>\n

The strength of concrete is a measure of its ability to resist loads. It is affected by a number of factors, including the water-cement ratio, the fineness of cement, the curing time, and the size of aggregate.<\/p>\n

The water-cement ratio is the ratio of the weight of water to the weight of cement in a concrete mix. A higher water-cement ratio results in a weaker concrete, while a lower water-cement ratio results in a stronger concrete.<\/p>\n

The fineness of cement is a measure of the size of the cement particles. A finer cement will result in a stronger concrete, as the smaller particles will be able to interlock more effectively.<\/p>\n

The curing time is the amount of time that concrete is allowed to harden before it is put into use. A longer curing time results in a stronger concrete, as the concrete has more time to develop its strength.<\/p>\n

The size of aggregate is the size of the stones or gravel that are used in a concrete mix. A larger aggregate will result in a weaker concrete, as the larger particles will not be able to interlock as effectively.<\/p>\n

In conclusion, the strength of concrete increases with an increase in the fineness of cement.<\/p>\n","protected":false},"excerpt":{"rendered":"
