Concrete is a composite building material made from a combination of aggregate and cement. The limitation of concrete material, in this case, is a fine aggregate (river sand). The utilization of sea sand as an alternative to fine aggregate in the manufacture of concrete is     motivated by the availability of sea sand in nature in very large quantities. This study aims to determine the comparison and how much the compressive strength of concrete produced when using sea sand. The test was carried out when the specimens were 7, 14, and 28 days old with the specimens used in this study were concrete cylinders with a diameter of 15 cm and a height of 30 cm. The results showed that the use of sea sand as a substitute for fine aggregate showed an average compressive strength in 7 days of 18.86 MPa, an average compressive strength of 14 days of 25.52 MPa, an average compressive strength of 28 days of 29.00 MPa. Then for the average compressive strength value of the use of river sand in 7 days is 17.17 MPa, the average compressive strength of 14 days is 23.24 MPa, the average compressive strength of 28 days is 26.41 MPa.

In this paper, the experiment about compressive strength of concrete using granulated blast furnace slag as fine aggregate was introduced. In this experiment, granulated blast furnace slag fine aggregates that were produced by two different steel factory and natural river sands that came from two different producing area were been used, and compressive strength of concrete for testing were four levels from ordinary strength level to high strength level. As results, the compressive strength of concrete that used granulated blast furnace slag as fine aggregate increase with increasing of concrete age as good as the concrete used nature river sand. At the early age of 3 days and 7days, whether water-cement ratio, the compressive strength of concrete using slag fine aggregate is always lower than concrete using river sand. At the long age of 91 days, the compressive strength of concrete using slag fine aggregate exceed the concrete using river sand when water-cement ratio was greater than 30%. The compressive strength of concrete using granulated blast furnace slag as fine aggregate can exceed 80N/mm2, the granulated blast furnace slag can be used in high-strength concrete.

The planning of concrete used 0,5fasand 60-100 mmslump, The testing was done at 28 days. The result of this study showed that for doing the inspection of sand quality physically, all the tests fulfilled the requirement setexcept in the inception of sieve analysis for Air Padang sea sand, which has a very fine grain. The highestincreased of concrete compressive strength was atLakok Sea Sand, which was 3.86% of the dunes, and 4.77% for the treatment of river sand for freshwater. For the treatment of Lakoksalt water on the dunes increased to 2.22% and on the river sand increased 3.74%. Air Padang Sea Sand has the biggest reduction the compressive strength of concrete, most notably in the treatment of fresh water on the dunes of 10.33% and 9.54% of the river sand. For salt water treatment, Air Padang Sea Sand had a greater reduction which was 14.61% of the dunes and 13, 33% of the river sand.

Compressive Strength Of Concrete

Concrete is the most widely used building material, which received hardening of mixture prepared from the coarse and fine aggregate, binding substance – cement and water. Cement and aggregate quality, v/c ratio of the mixture is determined by the uniformity of compacting properties of the concrete basic. Compressive strength of concrete is one of the most important properties of concrete. The paper examined a metal cord waste from recycled tires, effect on concrete properties, the optimal additive content was chosen. After the studies of the properties of the concrete with the different quantities of metal cord waste, it was determined that by increasing the amount of waste metal cord in the concrete the compressive strength of the specimens, density, predicted resistance to frost cycles increases, and absorption decreases.

PET (Polyethylene Terephthalate) plastic bottle waste is a material that takes a long time to decompose and will accumulate in the world for a long time. Therefore we need the utilization of the plastic waste. One way to reuse PET plastic bottle waste is to use it as an additive to the concrete mixture. The purpose of this study is to determine how much increase in the compressive strength of concrete to the addition of shredded PET plastic waste at 28 days of concrete. The variations in the addition of 0%, 0,2%, 0,4%, 0,6%, 0,8%, and 1% to the volume of concrete cylinders with 3 samples of concrete variations each. The results showed that the concrete with the addition of PET fibers by 0.2% experienced an increase in the compressive strength value of 1.31% from the compressive strength of normal concrete which was originally 22.251 MPa to 22.650 MPa. While the variation in the percentage of PET 0.4%, 0.6%, 0.8% and 1% decreased the compressive strength of the concrete. In PET fiber concrete 0.6% and 1.0%, although there is a decrease in the average compressive strength of the concrete, the value obtained exceeds the compressive strength value of the concrete plan, which is 20 MPa.

This present paper aims to investigate strength characteristics of cement mortar using natural sea sand as fine aggregate in different curing conditions. Research was carried out with making mortar mixtures by two types of cement, Portland Composite Cement (PCC) and Pozzolana Portland Cement (PPC) with tap water as mixing water. Characteristics of fine aggregate and strength of cement mortar use river sand (RS), sea sand (SS), and washed sea sand (WS) were observed. Further, specimens of cube mortar in size of 50 mm x 50 mm x 50 mm of six mortar mixture series were casted according to Indonesian Standard. At 24 hours after cube specimens were casted, cube mortar specimens were cured in three curing conditions such as tap water curing (TC), seawater curing (SC) and air curing (AC). After curing at certain period (3-day, 7-day, 14-day, and 28-day), cube mortar samples were tested in compressive strength. Results concluded that sea sand aggregate improve characteristic of mortar in compressive strength up to 28 days in all curing conditions, and there was no significant effect of type of curing water (TC and SC) on 28-day strength performance of mortar was obtained. In addition, sea sand could potentially be utilized as an aggregate in production of mortar and/or concrete.

In recent years, Nigeria has witness rapid development especially in the area of infrastructural development like roads, bridges, buildings etc. The conventional methods used in concrete mixing have its own peculiar problems, like time wasting, material wasting and errors. These problems have been the cause of structural failures which has given rise to loss of life and properties. Hence the need to development a method that will take care of all these anomalies witness in the conventional method. This work is aim at removing these anomalies by the use of Scheffes optimization method. This optimization method can predict the compressive strength of a concrete given the mix ratios and also predict the mix ratios required to give a compressive strength for a particular concrete made by completely replacing river sand with quarry dust. With this method it will be easy to predict the compressive strength of concrete based on the type of structure it is to be used for, there by eliminating the problems associated with structural collapse due to errors in concrete mixing by conventional method
