Question 31. How Did The Romans Get Water Up Hills Using Aqua Ducts?
Technically, the Romans had been not able to get water to transport uphill in a wellknown feel. All aqueducts flow water from an improved source (spring-fed streams in the mountains) to stop-customers at a lower elevation. The water flows almost absolutely downhill from the supply to the cease user. If the water needed to go a valley, the Romans could construct an arched shape with an elevated channel to pass the valley, but even this channel might have a vary mild downhill gradient that allowed water to glide closer to the quit person. If a large hill become of their way, the Romans might either divert the channel around the hill, dig a trench via the hill, or dig a tunnel through the hill, all whilst keeping a reasonably constant, slight downhill gradient in the direction of the stop user.
The handiest exception to the rule of thumb of a typically consistent downhill slope to the water channel is that specific tunnel segments, the Romans ought to build the tunnel as an inverted siphon (noted above) to pass a despair or valley and raise the water degree at the downhill side nearly to the extent of the uphill aspect. To do this requires a properly-sealed tunnel robust sufficient to withstand the expanded water pressure within the siphon. Note, but, that except for gaining a little bit of elevation if you gradual down speedy-moving water, you usually can not get water to glide out of the opening at a higher elevation than the inlet. So technically, even the Romans had been not able to get water to glide “up a hill”.
Question 32. Will Water Damage Concrete?

g) Results in growing older of systems
Question 33. How Do You Determine Specific Gravity Of Cement?
Cement is typically purchased as a powdery substance that is combined with sand, mixture, gravel, and water to form concrete. Since the cement itself is usually a powder, it's far hard to measure a wellknown cost for its unique gravity. In addition, when you consider that cement is normally now not used by itself, understanding its precise gravity isn't always PArticularly useful.
A extra useful question is “What is the standard density of concrete?” A rule of thumb answer is that normal cured concrete has a density of about 150 pounds in keeping with cubic foot. This consists of the weight of the cement, sand, mixture, and that PArt of the water that chemically binds with the cement to shape the concrete. Since water weighs about 62.Four pounds in line with cubic feet, concrete is ready 2.Four times as heavy. Thus, the particular gravity of concrete is ready 2.4. If you took cement and mixed it with water, you'll sooner or later have a hard lump of useless cement and it might additionally have a selected gravity of among 2 and a pair of.4.

The strategies that are involved in saving the shrinkage of the concrete includes:
(a) Spraying of water: On walls, and columns can be cured by sprinkling water.
(b) The moist covering of surface: may be cured via the usage of the floor with moist gunny luggage or straw
(c) Ponding: The horizontal surfaces such as the slab and flooring can be cured by way of stagnating the water.
(d) Steam curing: Prefabricated concrete devices, steam may be cured with the aid of passing it thru the units which are below closed chambers. It permits faster curing procedure and outcomes in faster recovery.
(e) Application of curing compounds: Compounds having calcium chloride may be implemented on curing floor. This keeps the floor wet for a completely long time.
Question 99. Sometimes The Side Of Concrete Bridges Is Observed To Turn Black In Color. What Is The Reason For This Phenomenon?
In a few instances, it is able to be because of the accumulation of dust and dust. However, for the general public of such phenomenon, it's far due to fungus or algae growth on concrete bridges. After rainfall, the bridge floor absorbs water and retains it for a positive time frame. Hence, this gives a good habitat for fungus or algae to grow. Moreover, atmospheric pollutants and proximity of flowers offer nutrients for their boom. Improvement in drainage information and application of painting and coating to bridges help to solve this trouble.
Question a hundred. What Reinforcements Are Used In The Process Of Prestressing?
The important varieties of reinforcements used in prestressing are:
(a) Spalling Reinforcement: The spalling stresses results in pressure at the back of the loaded vicinity of the anchor blocks. This results within the breaking off of the floor concrete. The maximum probably causes of such varieties of stresses are Poisson`s results pressure interoperability or via the pressure trajectory shapes.
(b) Equilibrium reinforcements: This type of reinforcements are required in which several anchorages exist in which the prestressing masses are implemented in a sequential manner.
(c) Bursting Reinforcements: These sorts of stresses occur in instances in which the pressure trajectories are concave toward the road of movement of load. In order to lessen such stresses, reinforcements in the form of bursting are required.
Question a hundred and one. What Are The Functions Of Grout Inside Tendon Ducts?
Grout in prestressing works serves the subsequent purposes:
Protect the tendon against corrosion.
Improve the last capability of the tendon.
Provide a bond among the structural member and the tendon.
In a case of failure, the anchorage isn't always challenge to all strain energy.
Question 102. What Is The Different Type Of Slump Test Indications?
Slump exams are accomplished to empirically measure the workability of fresh concrete. It is used to degree the consistency of the concrete. In popular, there are three unique types of slumps that occur in hunch assessments.
They are as follows:
(i) True Slump
(ii) Shear Slump
(iii) Collapse Slump
(i) True Slump: This sort of droop is characterised with the aid of the general drop in the concrete mass lightly with out seen symptoms of decay or disintegration. Shear Slump: It suggests that the concrete mix is poor in concord. This sort of droop results in segregation and bleeding. Henceforth, in the end, affecting the durability of the concrete.
(ii) Shear Slump: It suggests that the concrete mix is poor in cohesion. This form of slump leads to segregation and bleeding. Henceforth, in the end, affecting the sturdiness of the concrete. Collapse Slump: This sort of stoop is shows that the combination of concrete is actually too wet. The mix is considered to be harsh and lean.
(iii) Collapse Slump: This sort of slump is indicates that the mix of concrete is certainly too moist. The mix is taken into consideration to be harsh and lean.
Question 103. Is It Worthwhile To Carry Out Tests On Particle Density Of Soil Particles For Geotechnical Design?
Particle density of soils is defined by using the ratio of soil particle mass and soil particle extent. Depending on soil types, the variety of variant of soil particle density varies no longer notably, i.E. By means of 4%. Therefore, it may no longer be profitable to reserve laboratory tests and incur additional expenditure just to determine the debris density by way of spotting that the variant of debris density isn't always huge.
Question 104. What Are The Main Reasons For Conducting Pull-out Tests For Soil Nails?
There are in particular 4 reasons for this take a look at:
To test and verify the bond electricity among soil and grout followed throughout the layout of soil nails. This is the primary goal of conducting soil nail pull-out test.
To decide the bond electricity among soil and grout for future layout purpose. However, if this goal is to be achieved, the test nails must be loaded to determine the remaining soil/grout bond with an upper restrict of 80% of the last tensile strength of metal bars.
To take a look at if there is any slippage or creep incidence.
To test the elastic and plastic deformations of test nails. This is found in the course of the repeated loading and unloading cycles of soil nails.
