However, there are various problems in practical use of the sea sand for reinforced concrete and prestressed concrete ; durability, rust of reinforcing bars, strength in short and long period, contents of salt and shell. Based on results obtained from mortal test of sea sands in 20 places in Kagoshima pref., density and fineness modulus of the sea sand has much influence to the workability of the cement mortal, contents of salt and shell less influence. Contents of salt in the sea sand has much influence to the cement mortal strength in short period and long one. Content of shell in the sea sand has scarecely influence to the strength of cement mortal under 30% weight content.}, pages = {125--131}, title = {鹿児島県の海砂使用に関する実験研究}, volume = {19}, year = {1977} }
