(SEM-III) THEORY EXAMINATION 2018-19 BUILDING MATERIALS & CONSTRUCTION

This document is the B.Tech SEM–III Theory Examination 2018–19 question paper for Building Materials & Construction (Subject Code: RCE301) under Dr. A.P.J. Abdul Kalam Technical University (AKTU).
The uploaded PDF contains two pages, clearly divided into SECTION A, SECTION B, and SECTION C.
The paper carries 70 marks, and the allotted time is 3 hours.

The exam evaluates a student’s understanding of common building materials, construction components, flooring, ventilation, joinery, traps, lintels, air conditioning, staircases, and essential construction practices.

SECTION A — Short Questions (2 × 7 = 14 Marks)

(Visible on Page 1)

Section A contains seven brief questions, each worth 2 marks.

Topics include:

Meaning of P.V.C.N.                                              What is terra-cotta

Why turpentine should be taken in minimum quantity for exterior works

Difference between escalator and lift                  Factors affecting flooring material choice

Suitability of clay products for construction         Meaning and importance of preservation of timber

Each question is clearly printed in the Section A list on Page 1.

SECTION B — Long Questions (4 × 7 = 28 Marks)

(Shown on Page 1, after Section A)

Students must attempt any four questions.
The questions require explanation, sketches, and construction-based detailing.

Topics include:

Properties and uses of timber                  Classification & properties of stones used in construction

Methods of seasoning timber                Requirements and types of floorings

Explaining roof coverings                        Classification of stairs and requirements of a good staircase

Types of doors and windows commonly used

These questions test deeper understanding of materials, construction techniques, and structural components.

SECTION C — Applied Construction Questions (Each 7 Marks)

(Page 2)

Section C contains Question 6 and Question 7, each having two alternatives (a or b).
Students must attempt one part from each question.

Q6 — Ventilators / Lintels

(Shown on Page 2)
