Question : GATE 1992 

 The following compound of cement contributes most to the strength of concrete:

(A)       Calcium Aluminate

(B)       Dicalcium Silicate

(C)       Tricalcium Silicate 

(D)       Gypsum

Answer: (C) Tricalcium Silicate

·         Dicalcium aluminate gives initial strength and hardness to concrete.

·         Tricalcium aluminate gives strength after one week and contributes to maximum strength.

·         Gypsum retards the setting time of concrete.

Question

Consistency of cement is measured by

(A) Pycometer                                                 (B) Slump Cone

(C) Universal Testing Machine                        (D) Vicat’s Apparatus

Answer:  D. (Vicat’s Apparatus)

A cement paste is said to be of normal consistency when a 300 gram, 10-mm-diameter Vicat needle penetrates 10 + 1 mm below the surface in 30 seconds.

Slump cone test is done to measure workability of concrete.

Universal Testing Machine (UTM) measures compressive strength of mortar/concrete blocks.

GATE Architecture Question

Regarding three Books- Townscape by Gordon Cullen

                                            - Image of City by Kevin Lynch

                                            - Defensible Space by Oscar Newman

Serial Vision: English architect and urban designer Gordon Cullen developed the term serial vision to describe what a pedestrian experiences when moving through a built environment. (Townscape)

·         Occupied territory:  « Shade, shelter, amenity and convenience are the usual causes of possession. The furniture of possession includes floorscape, posts, canopies, enclaves, focal points and enclosures ». (Cullen, 1971, p.23)

·         Viscosity:  « Where there is a mixture of static possession and possession in movement, we find what may be termed viscosity: the formation of groups chatting, of slow window-shoppers, people selling newspapers and so on. » (Cullen, 1971, p.24)

·         Enclave:  « The enclave or interior open to the exterior and having free and direct access from one to the other is seen here as an accessible place or room out of the main directional stream  » (Cullen, 1971, p.25)

·         Enclosure:  «  It is the basic unit of the precinctual pattern ; outside, the noise and speed of impersonal communication which comes and goes but is not of any place. Inside, the quietness and human scale of the square, quad or courtyard ». (Cullen, 1971, p.25)

·         Focal point:  « Coupled with enclosure (the hollow object) is the focal point, the vertical symbol of congregation. In the fertile streets and market places of town and village it is the focal point (be it column or cross) which crystallizes the situation, which confirms ‘this is the spot. Stop looking, it is here ». Cullen, 1971, p .26)

Urban Imageability: “Image of City” by Kevin Lynch

·         District: Area of homogeneous character recognized by clues.

·         Node: Strategic foci into which observer can enter.

·         Landmark: Important location.

·         Pathway: Act as lateral reference and often path as well.

Defensible Space: The defensible space theory of architect and city planner Oscar Newman encompasses ideas about crime prevention and neighborhood safety. The theory developed in the early 1970s, and he wrote his first book on the topic, ‘Defensible Space’ in 1972. Newman focused on explaining his ideas on social control, crime prevention, and public health in relation to community design.

• disabled persons = 1:12
• pedestrian only ramps = 1:15 to 1:20

GATE Architecture/Planning 2016

Question: As per the IRC standards, the minimum width (in m) of a two lane urban carriageway without a   

                raised kerb is

(A) 6.0                                                             (B) 6.5

(C) 7.0                                                             (D) 8.0

Answer: (C) 7.0

·         The roads are grouped as Single lane (3.5 m), intermediate lane (5.5 m), Double lane (7m with kerb or 7.5 m without kerb) and multiple lanes (addl. 3.5 m for each lane) depending upon the width of Carriageway. On village roads, the width may be restricted to 3 m.

Government Roads

·         NH: Main highways running through the length and breadth of the Country connecting major ports, State Capitals, large industrial and tourist center.

·         SH: Arterial routes of a State linking District Headquarters and important cities within the State and connecting them with NH or Highways of the neighbouring States.

·         MDR: Major District Road, Important roads within a district serving areas of production and 
markets and connecting those with each other or with main highways

ODR: Other District Road,  Roads serving rural areas of production and providing them with outlet to market centers, taluk headquarters, Block Development headquarters or other main roads.
