slabs of concrete som long are laid end to
end to form a roadway How large a gap
should be allowed b/w adjacent slabs at
-20°C so that they do not buckle when
temperature reaches +50°C 2 ?
co-efficient of linear expansion of concrete
is lox 106001​

Answer 1

Answer:

the slab would expand by amount=Lt*coeff of expansion*change in temp

Explanation:

200*10*10-6*70=.14meter
