4.3.7.9

Storage on the Site of the Works

Aggregates of different nominal sizes shall be stored separately and in such a manner as to prevent
segregation, contamination, and intermixing of different materials. Aggregates from different sources
shall not be mixed nor stored in the same pile.

Aggregate stockpiles shall be on hard, clean surfaces with not more than 5 % slope. Stockpiles shall
be built and removed in layers not exceeding 1 m in thickness and the centre of the storage area
shall be free of excess moisture. Aggregate that has become segregated or contaminated with
foreign matter during storage or handling shall be rejected, removed, and reprocessed or replaced
with material of acceptable quality. Aggregates shall be stored in sufficient quantity to ensure that
no interruption of concreting work occurs.

Aggregates exposed in coastal regions with marine salty air shall be covered to protect them from
salt contamination.

4.3.8

Water for Concrete Mixing and Curing

Unless otherwise authorised in writing by the Engineer, only water from a municipal potable water
supply system shall be used for mixing concrete and other products containing cementitious material.
Similarly, only potable water may be used for curing concrete and  cementitious material products
during  the  first  24  hours  after  pouring.  Later,  fresh  water,  Sulaibiyah,  including  recycled  sanitary-
effluent  water,  or  other  water  containing  not  more  than  4,000  ppm  dissolved  solids,  of  which  not
more than 1,200 ppm may be chlorides, may be used for curing. All water for use with cementitious
material shall be free from detrimental concentrations of acids, alkalis, salts, sugar, and other organic
or chemical substances that could impair the durability and strength of the concrete or the imbedded
steel.

Water shall enter the mixers at as low a temperature as possible. Every effort shall be made to
protect water pipes and tanks from the sun, such as burying, shading, insulating, or painting pipes
white.

4.3.8.1

Tests and Acceptance

Water used shall be sampled, tested, and in compliance with AASHTO T 26. If the water contains
substances that cause discolouration, unusual or objectionable smell or taste, or other suspicious
content, the Engineer may require that the Contractor provide test results that document the
acceptability of the water per these Standard Specifications and requirements of Table 4-15.

Water used in concrete works shall have a pH between 5.0 and 8.0.

Classification of Concrete

Concrete classes used shall be as noted in the Contract plans, the particular specifications, and as
described in these Standard Specifications. Concrete classifications shall be per BS EN 206-1 and
BS 8500-1 and as modified by the following definitions.

a. Compressive strength class of a concrete mix

will be designated as ”Xyy/zz” on the Contract

plans and in these Standard Specifications, where:

Prefix: ‘X’ = ‘C’ for normal-weight and heavyweight concrete or ‘LC’ for lightweight concrete

‘yy’ = Minimum 28-day cube strength in N/mm

’zz’ = nominal maximum size of aggregate in mm

b. Class of concrete may be abbreviated by omitting the aggregate size, e.g. C20 in place of

C20/20.

The compressive strength classes are in N/mm

(MPa). Typical concrete classes include:

•

Normal Concretes: C15, C20, C25, C30, C35, C40, C45, C50, C60

•

Lightweight Concretes: LC15, LC20, LC25, LC30, LC35, LC40, LC45, LC50, LC60

7.2 Guardrails and Attenuators

7.2.1 Guardrails

7.2.1.1

Description

This work consists of furnishing, constructing, modifying, removing, and resetting guardrail systems,
which shall include, but not by way of limitation, guardrail, posts, transitions, terminals, and anchors.
Type of guardrail to be used shall be shown on the Contract plans and as approved by the Engineer.
Guardrails specified herein include the w-beam, thrie - beam and wire-rope types.

Completed guardrail shall present a uniform appearance free of scars, stains, or corrosion and shall
not show any visible deviations from line and grade. Posts shall be straight and vertical. Guardrails
shall not be warped but shall be in a vertical plane, aligned parallel to the road centre line except at
end treatment sections.

7.2.1.2

Materials

Certificates of compliance for guardrail materials shall be submitted by the Contractor. When directed
by the Engineer, the Contractor shall provide samples of guardrail elements to be tested for
compliance with the physical and chemical property requirements detailed in these Standard
Specifications.

All materials shall be subjected to inspection and sampling at the fabricating plant, warehouse or
after delivery to the site of construction.
