“…Samples of concrete that were made in the laboratory were more resistant to seawater than samples that were made on-site showed by the investigator [12]. This study examined OPC with SF and silpozz on marine self-compacting concrete strength and chloride content [13]. By analyzing the factors that influence the mechanical behavior of concrete, such as the size and shape of the particles, the concentration and orientation of the particles, and the distribution of the particles, as well as the topology of the cement-concrete matrix, one can determine the microstructural properties of concrete.…”

This study aimed to determine the strength and chloride content of marine concrete if fly ash and silica fume were used to replace a portion of the conventional Portland cement (OPC). The study was done so that these goals could be reached. W/C of 0.42 to make M30 grade concrete. Even though the number of parts that go into making OPC concrete is the same, using SP cuts the amount of water needed to make mixed concrete by 20%. Several different experiments that were done with different mixtures back up this conclusion. Compressive strength, flexural strength, and split tensile strength are the three types of strength that have been looked at. For the durability test, water-soluble chloride (WSC) will be used. SEM, which stands for scanning electron microscopy, will be used for the microstructural analysis. According to the test results, the compressive strength of concrete that had been treated with dosages of SP and had 10% fly ash showed a degradation factor (DF) of less than 5% after being exposed to the elements for a year. Even though the concrete had been out in the weather, this was still the case. After 90 days, both the split tensile strength and the flexural strength have a DF of 0.95 percent, but the flexural strength only has a DF of 0.5 percent.
