1) . The only local materials available In any quantity
arc sand and rock. The latter Is not suitable for
sails of the required height, and in any case the
use of rock would entail using a large quantity of
cement. The rock will be crushed and used as
aggregate.
2) . It is understood that the use of concrete is to be
kept as low as possible, owing to cement shortage;
and that bricks will be used. It is proposed to
erect sheath walls of brickwork built in cement
mortar (1 : 3), on reinforced concrete foundations
(1:2:4).
3) . The possibility of losing certain local materials
which are obtainable in small quantities is being
investigated, 'iflit for tha purposes of estimating
requirements it must be assumed that all necessary
bricks, cement and steel will have to be imported
1) . At the Refinery» i»a. for 90t of tho work, rock exists
close to the ground level. Concrete foundations
2*O'* wide, average depth 2*6*, reinforced with i*
rods are proposed - see attached blueprint.
2) . At Sitra and Sellaq the ground Is soft and it will
be necessary to spread the weight, with a consequent
increase in concrete and reinforcement. Bearing
tests are being carried out by the Company
smii
1) . The first stage will consists of a brickwall, 18"
tiJLck, 10•0" high to each tank. As the foundations
product 1 •6" above ground, this will give protection
to 11 *6'*.
2) . It is rocomended that tho final total height of
wall shall be SO'O*. By limiting the height to
this figure the thickness of wall at base need not
exceed 18". If 30*0" Is over to bo exceeded, a
wall thicker at the base will have to bo constructed
NOW; thereby increasing the time to give this initial
protection by approximately 20$. The tanks vary in
height from 25'0" to 46*0*', but are seldom full; and
it is reasonable to assume that a 30*0* sheath will
to all intents and purposes give complete protection.
. The complete 30*0" shaath will be as follows -
