In the water supply project of Turkish Republic of Northern Cyprus (TRNC) from Turkey, high-density polyethylene (HDPE) pipes of total 80 km in length are to be used.These pipes are suspended 250 meters below the sea level by means of precast concrete anchor blocks that are positioned on the seabed at different depths, at a maximum depth of 1431 m.The mix design of anchor blocks are made conforming to ACI 318 technical specifications and designed against sea water effects.The cement type used is slag cement that is highly resistant to effects of sea water and high-strength self-compacting concrete is used for ease of placement.According to the specifications of the pre-cast concrete anchor blocks, the concrete should have a maximum w/c ratio of 0.35 and a minimum strength class of C40/50.Moreover, as this strength class of concrete has a high cement dosage and the smallest dimension of the anchor block is more than 1.0 m, the concrete should be treated as mass concrete.With the specified criteria and given properties, the concrete is required to have a 50 years of service life against the effects of seawater.
