Investigation On The Characteristics Of Cornstalk Ash Blended Cement
Analysis of investigation on the characteristics of cornstalk blended ash cement was carried out based on the interest of coming out with a good pozzolanic material with all required cement properties. Hence, the supposed competitive demand relationship between cement products in construction works has been majorly wined by cement and this makes people to depend mostly on it despite the increase in price and some with inadequate properties.
In an attempt to reuse and convert agro wastes into useful materials for the construction industry, this research considered the application of corn stalk ash (CSA) as partial replacement for ordinary Portland cement (OPC) in the production of concrete cubes.
The study investigated the oxide composition of CSA to ascertain its suitability as a pozzolanic material. Some properties of cement with CSA as a replacement for OPC were examined.
The results showed that CSA is not a good pozzolana as it does not satisfy the requirement for use as a pozzolana according to ASTM C618(2005). The compressive strength of the specimens with replacement levels at 10% and 20% cured for periods of 7–28 days was lower at early curing time but improved significantly at later age.10% replacement level did not show increased strength compared to 20% CSA at 28 days curing period. Density decreased with increasing ash content, water absorption rate increased with increased CSA contents, while abrasion resistance increased with increasing amount of CSA substitutions. The test results revealed that
CSA concrete cubes can attain higher strength than the conventional ones at longer curing periods, due to its pozzolanic reactions.

1.1 Background to the study
Various blends of cement utilized in construction are portrayed by their physical properties. Some key parameters control the nature and quality of cement. The physical properties of good cement are based on; Fineness of cement, Soundness, Consistency, Strength, Setting time, Heat of hydration, Loss of ignition, Bulk density, Specific gravity (Relative density). In addition, cement has a very high cost in many developing countries like Nigeria and its usage cannot be sustained. The need for moderate structure materials in giving satisfactory lodging to people of the world has turned into the real worry of researchers. The expense of traditional structure materials keep on expanding as most of the populace keeps on falling beneath the destitution line. This consequently requires the look for elective neighborhood materials as aggregate or fractional swap for concrete (Adesanya and Raheem, 2009; Akinwumi and Aidomojie, 2015; Raheem & Adedokun 2017). The research has led to the discovery of the potentials of using industrial by-products and agricultural wastes as replacement of some cement materials. Agricultural and industrial wastes possess pozzolanic properties used in cement replacement. The application of agro and industrial wastes in the production of cement is an environmentally friendly method of disposal of large amounts of substances that would have constituted pollution to land, water and air. The agricultural and industrial wastes that possessed pozzolanic characteristics and which had been studied and applied as partial replacements for cement are Rice husk ash [6-9], Corn cob ash [4, 10-12], Waste burnt clay [13-14], Hair fibre  and Saw dust ash [16-17]. The saw dust ash (SDA) which has been proven to be a pozzolanic material was used as a partial substitution for OPC in this study. Many researchers have argued that concrete is one of the major materials used for radiation protection in facilities. The radiation protection feature of concrete depends on its components. Cement production is one of the important sources of carbon dioxide emission to the atmosphere. CO2,which is a greenhouse gas, contributes about 65% of global warming (Vijayakumar, 2013; Raheem & Adedokun 2017). The high energy demand as well as the emission of carbon dioxide, which caused global warming and depletion of limestone deposits are the major challenges associated with cement production.
In the recent years, there is great interest in replacing a long time used materials in concrete structure by new materials to produce cheaper, harder and durable concrete. Abdelrahman& El-Awney (2015).The raw materials for cement production are limestone (calcium), sand or clay (silicon), bauxite (aluminum) and iron ore, and may include shells, chalk, marl, shale, clay, blast furnace slag, slate. Chemical analysis of cement raw materials provides insight into the chemical properties of cement.
Corn, also known as maize, is one of the most successful cereal grasses of all time. It has been under human cultivation for over 10,000 years and has spread itself into every niche of commercial agriculture (Adesanya, & Raheem (2009). Maize crop started as a subsistence crop in Nigeria and has gradually risen to a commercial crop on which many agro-based industries depend on as raw materials (Iken, and Amusa, 2014).Corn stalk is a waste product obtained from maize plant, which is the major cereal crop produced in sub-Saharan Africa. Therefore, this research investigated the use of Corn stalk as a partial replacement for ordinary Portland cement in the production of concrete cubes. It includes the determination of the oxide, composition of the CSA, evaluation of the compressive strength, density, water absorption, crushing strength of the concrete and the abrasive resistance of the concrete cubes.
1.2 Problem statement
A major challenge in the constructions in the world today is access to good and quality cements with right proportions of its physical properties. The high price of good cement with balance property ratio has made it difficult for people to acquire it, hereby leading to usage of poor quality cement which later affect the construction. This study examined the physical properties of ordinary cements alongside blended cornstalk ash and how it improved the physical properties without unnecessary increase in the cost for effective and standard construction.
1.3 Aim of the study
The aim of this study is to investigate the characteristics of corn stalk blended cement as a partial replacement for ordinary portland cement.
1.4 Objectives of the study
The main aim of this study is to investigate the characteristics of corn stalk blended cement as a partial replacement for ordinary portland cement while the objectives of the study are:
- To ascertain the characterization of corn stalk ash.
- To determine of the effects of corn stalk ash on physical and mechanical properties of blended cement mortar.
There were several motivations for this study. Although few studies have investigated on things related to the properties of cornstalk ash and other supposed waste of agricultural materials. To the best of my knowledge, there was no definite assurance of complete adequate physical properties in ordinary cement until now. Additionally, analyzing a good access and usage for construction will provide better constructions as well as reducing the number of collapse building in the world. Addition of blended corn stalk ash has further enhanced the physical properties generating a better result for construction at a lower price. In an attempt to reuse and convert agro wastes into useful materials for the construction industry, several research had been carried out on the application of corn stalk ash (CSA) as partial replacement for ordinary Portland cement. The study investigated the characteristics of corn stalk ash blended cement and ascertain its suitability as a pozzolanic material.
This study centers on the characteristics of corn stalk ash blended cement. Base on the limitation of the study, this research investigated the use of Corn stalk as a partial replacement for ordinary Portland cement in the production of concrete cubes. It includes the determination of the oxide, composition of the CSA, evaluation of the compressive strength, density, water absorption, crushing strength of the concrete and the abrasive resistance of the concrete cubes.
Conclusions and Recommendation
This study has dealt tremendously on the investigation of the characteristics of cornstalk ash blended cement. The findings of this research has led to the following conclusions:
- The study revealed that Corn stalk ash (CSA) is not a good pozzolanic material because it does not satisfy the standard specified by ASTM C618(2005).
- The compressive strength of the concrete cubes increased with curing period and amount of CSA at early curing time, but the strength improved significantly at the later curing time. Results indicate that only 20% CSA replacement at 28 days curing is adequate to enjoy maximum benefit of strength gain.
The major findings of this study has prompted this recommendation for the use of cornstalk ash blended cement.
Concrete cubes made with 20% CSA replacement and cured for 28 days is therefore recommended for use because of its higher strength as compared to the control, which contains 100% ordinary cement. This recommended CSA replacement can be used in residential building, residential landscaping , especially in residential drive ways, walk ways and pedestrian walk ways on highways.
