What you mean by porous concrete?1 AnswerAgricultural Engineering Gate: The elevations of pressure gauge and porous cup of the tensiometer installed in unsaturated zone are 145.8 m and 144.2 m, respectively. Pressure measured at the gauge is -19.62×103 N m-2 . The specific weight of water is 9810 N m-3 . The estimated pressure at the porous cup is ________ N m-2 .0 AnswerAn isolated concrete pavement slab of length L is resting on a frictionless base. The temperature of the top and bottom fibre of the slab are Tt and Tb, respectively. Given: the coefficient of thermal expansion = α and the elastic modulus = E. Assuming Tt > Tb and the unit weight of concrete as zero, the maximum thermal stress is calculated as0 AnswerA reservoir model consisting of two porous matrices M and N, separated by a fracture, is shown in the figure. The matrices are strongly water-wet and are saturated with oil of specific gravity 0.8. Water is injected only in the fracture at injection well A. If the Reynolds number for the flow in the fracture conduit is assumed to be less than unity, which one of the following force will dominate oil recovery from the porous matrix M during the water-flood operation?1 AnswerA reservoir model consisting of two porous matrices M and N, separated by a fracture, is shown in the figure.

If the Reynolds number for the flow in the fracture conduit is assumed to be less than unity, which one of the following force will dominate oil recovery from the porous matrix M during the water-flood operation?1 AnswerWhen a specimen of M25 concrete is loaded to a stress level of 12.5 MPa, a strain of 500×106 is recorded. If this load is allowed to stand for a long time, the strain increases to 1000×106 .0 AnswerThe deformation in concrete due to sustained loading is (GATE-CIVIL-Engg-2018)1 AnswerTie bars of 12 mm diameter are to be provided in a concrete pavement slab. The working tensile stress of the tie bars is 230 MPa, the average bond strength between a tie bar and concrete is 2 MPa, and the joint gap between the slabs is 10 mm.0 AnswerOne of the key assumptions made by Dupuit-Forchheimer about the flow behavior in the porous medium towards subsurface drains is (GATE-Agricultural-Engineering-2018)0 AnswerConsider the following statements for air-entrained concrete: (i) Air-entrainment reduces the water demand for a given level of workability (ii) Use of air-entrained concrete is required in environments where cyclic freezing and thawing is expected Which of the following is TRUE? - gate civil 2017 1 AnswerSpecific discharge of 1 cm per day is observed in a porous medium where hydraulic head difference is 0.5 m and flow length is 20 m. Calculate the hydraulic conductivity (in m/day).

Assertion (2): The equivalent alkali content (in terms of Na2O equivalent) for a cement containing 1% and 0.6% of Na2O and K2O, respectively, is approximately 1.4% (rounded to 1 decimal place). Which one of the following statements is CORRECT?0 AnswerSelect the related word/letters/number from the given alternatives. Coal : Black :: Chalk : ?1 AnswerArchitecture and Planning : A 5m × 5m × 3m room has four 230 mm thick external brick walls. Total wall fenestration is 10 sqm. The temperature difference between indoor and outdoor is 2 degC. The air to air transmittance values for 230 mm thick brick wall and 200 mm thick aerated concrete block wall are 2.4 and 1.7 W/sqm degC respectively. If the brick walls are replaced with the aerated concrete block walls, then the change in conductive heat flow through the walls is _________W.0 AnswerWhich one of the following is categorised as a long-term loss of prestress in a prestressed concrete member? -Civil Engineering-gate-20121 AnswerWhat is workability in concrete?1 AnswerHow does the moisture of concrete affect the durability of the structure?1 AnswerWhat all are the aggregates used for concrete making?1 Answer
