Question { Parsvnath, 1858 }

State the type of roads and compare the advantages and disadvantages?


Answer

most commonly 2 types of pavements are used,
1) rigid-pcc
2)flexible-bitumen

1) rigid pavements, ie. pcc, is costly. they require low maintenance, the construction speed is very slow.
2)flexible pavements, ie. bitumen, is low cost as compared to rigid pavements. they requires periodical maintenance, the construction speed is faster as compared to pcc road construction.

Question { NM Caramoan Builders, 3767 }

Why we test compressive strength after 28 days..?


Answer

after 28 days 99% of characteristics compressive strength will be achieved( rate of hydration is faster). after 28 days in a long course of time, say 1 year, the balance 1% strength will be achieved( rate of hydration is very slower). it is not desirable to keep the cube for 1 or 2 years and test , if the full strength is achieved. so we test after 28 days.

Question { Bohra Industries Limited, 3677 }

How to calculate water tank capacity in Ltr


Answer

In 1 m3 of volume we can accommodate 1000 kg ie.1000 liter of water. so that first find the volume of the container in m3 and multiply that with 1000, you can get the quantity of water
in liters.
ex. if the volume of the container is 3 m3, the water can be stored is = 3*1000=3000 liter.

Question { IIT, 3187 }

we do not provide reinforcement bar through the centre of a column.why?


Answer

basically column is a compression member. maximum compression load sustained by column and transferred to foundation through the axis of the column. steel is not good in compression. because of lateral loads and eccentric loads the tensile stress created only around the center but not up to the center. because of that only around center reinforcement is enough to take care of the tensile stress.

Question { NCCL, 8995 }

how to calculate shuttering measurement of beam and slab


Answer

shuttering work of horizontal members are generally called as, centering. centering works are measured in m2. shuttering area = the area of slab (take clear spans for finding area) + total depth of the beam (no. 1 and 3 which are parallel to each other) * the clear span of the slab which is parallel to the no. 1 and 3 beams + width of the beams * total center to center length of the beams + (total depth of the beam + total depth of the slab) * total length of all the beams.

Question { NCCL, 8995 }

how to calculate shuttering measurement of beam and slab


Answer

sorry, sum also the, total depth of the beam (no. 2 and 4 which are parallel to each other) * the clear span of the slab which is parallel to the no. 2 and 4 beams with the above formula.

Question { Appco, 2402 }

how the find the quantity of water used to make 1 cubic meter concrete mortor


Answer

first we should know the ratio of the cement mortar, then find the quantity of cement. you should select a w/c ratio. using the water cement ratio and cement content (in kg) per cubic meter of mortar you can find the water content. NOTE: 1 kg of water is 1 liter of water.
