Journal of Emerging Technologies and Innovative Research, 2019

In any construction brick masonry is very much of used to make a walling units and in that cement mortar is one of the important ingredients it makes up as little as 7% of total volume of brick masonry. Brick masonry also prevent moisture and air penetration so in short cement mortar is very much of use in brick masonry so if change certain amount of cement with any other material which is less in cost than cement. The other material reduces the danger to the environment so it is essential to check that how much amount of cement is replaced by various materials. In India carbon black powder are generated from the different rubber industries. This waste, causing major environmental problem due to their disposal. The goal of this study is to replace the cement by carbon black powder to reduce the waste. In this study the different proportion of carbon black powder replaced with cement is 0%, 5%, 10%, 15%, 20%, 25% and 30% by weight. The compressive strength test carried out at 7, 14 and 28 days and water absorption test is carried out in 28 days. As a result, this investigation work is done on mortar for optimum proportion of the partial replacement of cement by carbon black powder.

The present work contributes to the difference between mechanical properties of lightweight cement mortar by using common waste such as coconut shell powder, wood waste and sea shell powder as the partial replacement of sand. These waste materials can be found easily and I tried to make better use of them in this present work. The mechanical properties conducted were workability, compressive strength test and split tensile strength test. The results were concluded by describing the best material for replacement of sand and its optimum quantity which is to be added to produce lightweight cement mortar. Lightweight cement mortar can be used in cases of underwater construction, for better heat resistance, eco-friendly construction. In, by and large, the mortar is plastic liquid-like structure comprises of OPC cement or Ordinary Portland Cement, water and Fine aggregate. The common mortar can be used for masonry works in most of the cases. But to impart special characteristics to the common mortar we need to add some ingredients such as fly ash, rice husk ash, metakaolin etc, so, in this present work, I used different waste material as a partial replacement for the fine aggregate or sand.

The aim of this project work is to demonstrate the effect of cementitious materials on properties of mortar. For construction purposes Mortar mix is used as binding material. The most commonly used mortar ingredients to make different types of mortar are cement , sand, lime, water etc. It is known that the consumption of natural sand as fine aggregate in mortar production is very high and many developing countries are facing some problems in the supply of natural sand in order to achieve the increasing demands of construction development. For getting a good mortar mix, it is very important to use quality ingredients. Without good ingredients, it is not possible to get the desired quality of mortar mix. Therefore this study investigates the use of nano silica , fly ash , GGBS to form mortar. This study introduces a mode of construction by partially replacing the waste materials. Since these materials are obtained from waste products of various industries. By reviewing various literature we acquired the knowledge about mix designs .and by the result we get to know about effect of silica, fly ash and GGBS on properties of mortar. The expected results are that by adding these materials the compressive strength of mortar must increase and the consistency must increase with decrease in cement content.

Excessive use of cement makes the price of construction projects expensive. Mortar making using high amounts of cement also has the potential to increase the price of the construction. This study discusses the use of agricultural waste as a substitute for cement in mortar production. The waste used in this study was bagasse ash, fuel ash palm oil, and rice husk ash. Each waste is added as much as 25%, 50% and 75% which are then tested for mechanical properties such as water content, unit weight, absorption, and IRS. Compressive strength was tested when the mortar was 28 days old with a cube-shaped specimen with a size of 50 mm x 50 mm x 50 mm. From the test results, it was found that all of this waste can be used as a substitute for cement. To produce a compressive strength of 100 kg/cm2 can add each waste with a percentage range of 10-12% of the weight of cement.

The lime gathers all the qualities, required from building materials within the framework of the sustainable development (Low grey energy and absorption of CO2 during the hardening. However, lime presents certain disadvantages like relatively slow setting and carbonation, low mechanical performances compared with cement and high drying shrinkage. For this study, the charcoal and the crushed bricks were added with different proportions to the lime mortar in order to assess the impact on the physical and mechanical properties of this mortar. The primary focus was to assess the differences in setting time and investigate the reasons behind the measured differences. In parallel, the mortar prisms 4 × 4 × 16 cm was analyzed in the laboratory conditions in view of mechanical properties and shrinkage phenomena. Finally, a RILEM Test Method II.4 is used to measure water absorption under low pressure and permeability to water of the lime mortar.
