My #ulog post for today - Curing of Hardened Concrete Cubes in Water for 90days Starts Today

My first ulog post was a goal.

Sharing my day to day activities and experiences here on steemit is a goal.

Looking forward to having an interesting day the next day is a goal.

That am lucky to have #surpassinggoogle here on this great platform with us is a goal.

I am just gaining strength, i think it's quite good when you eat a good solid food like Semovita and Vegetable soup after going through a hectic day just to pay the day off before you lay your head on bed. I said this because that is what i just finished eating for dinner.I hope you guys ain't salivating for that already. Would have loved to show you a picture but the food was just too sumptuous and palatable that i had to forget to take one when eating.

Basically, I told you guys yesterday that i would be removing those concrete cubes that i helped in casting with my friend from the mould. We actually did that and thank God that was not food so i did not forget to take pictures to show these lovely steemians on here ... Lol!!!

It was quite an easy task to remove the (150 × 150 × 150)mm and (100 × 100 × 100)mm hardened concrete from the wooden moulds because the wood was lubricated with a lubricant yesterday before pouring the wet concrete in them plus one part of the wooden mould were fastened or tightened making use of a screw. so what we did was that we loosed the screws from the wood and detached a part of the wooden mould and that made it easy to removes the hardened concrete from their wooden moulds.

Unlike the wooden moulds, it was the direct experience of going through hell while we were trying to remove or detach the (300 × 150)mm hardened concrete from their cylindrical plastic pipe moulds. However, we finally won the battle of the angels and made it to heaven by succesfully detaching the hardened concrete from the cylindrical pipe moulds. That is the main reason you should never accept defeat, instead draw back a little and come back even stronger. Do not quit until you made it to success. To keep going in life, you need determination, commitment, and prayer.

We allowed the hardened concrete to dry for some more minutes and put them one by one into the water tank filled with clean water to start the 90days curing in water.

Steeming is a goal for all

Kindly assist me financially with my final year project sirs/ma.

ESTIMATED COST IMPLICATION

This is calculated in Nigerian Naira and then converted to steem dollars of which the equivalent in sbd is approximately 90sbd at present exchange of 1sbd to #950 of which I have gotten about 20sbd and have about 70sbd more to go.

Any support will be much appreciated Sir/Ma.

Thanks

MATERIALS NEEDED

Based on my mix design ratio proportion of 1:1:2 for concrete and 1:9 for mortar, I will need the following: I will be casting 60 cubes mould of concrete and 60 cubes mould of mortar

• 3 bags of cement = 3 x 2500 = #7,500

• 0.203 tonnes of coarse aggregate = 3000 x 0.203 = #600

• I have gotten fine aggregate for free from an on-going building project on campus.

• Waste glass: I have gotten enough from bars and dumpsites and started grinding into powder

MOULD FOR CONCRETE CUBES AND MORTAR CUBES

I would need three different mould sizes of 150x150x150mm wooden mould, 100x100x100mm wooden moulds and 300x150mm circular pipes.

• 150x150x150mm wooden moulds: I would need 40 of this but I am going to make do with 20 since I am not casting at once. = 20 x 500 = #10,000

• 100x100x100mm wooden moulds: I would need 40 of this also but I am going to make do with 20 = 20 x 500 = #10,000

• 300x150mm circular pipes: : I would need 4 full length of this since it cannot be re-used = 4 x 2100 = #8,400

TESTS TO BE CARRIED OUT

• Chemical analysis of Sand, Cement and recycled glass powder: I am going to be doing my chemical analysis on 9 parameters which includes; silica, alumina, iron oxide, calcium oxide, magnesium oxide, sodium oxide, potassium oxide, sulfur trioxide and loss on ignition. Each of which is #500 each except loss on ignition which is #1,000 = (500 x 8) + 1000 = 5000 x 3 = #15,000

• Fresh state properties: The estimated cost for properties such as setting times, consistency, workability, air content and shear strength = 2000 x 5 = #10,000

• Hardening properties: Cost of conducting test for hardening properties such as density, compressive strength, tensile strength, modulus of rupture and modulus of elasticity is not known yet but I think of budgeting maybe #10,000 for it.

• Durability properties: The cost of conducting test for durability properties such as water absorption, shrinkage properties, chloride resistance and sulphate resistanceis not known as well but I will budget about #8,000 for it.

• Physical properties: physical properties such as bulk density, real density, and modulus of fineness would be done in the school laboratory since the school have the equipments needed for its determination.

Transportation + Miscellaneous = #5,000

ESTIMATED COST IMPLICATION = #84,500 ( A total sum of eighty four thousand, five hundred Naira only)

Just as i have stated in my previous post the following ;

PROJECT TOPIC

Strength properties of mortar and concrete using waste glass as partial replacement for cement and fine aggregate.

ABSTRACT

The glass is widely used and one of the least recycled material in country like Nigeria. Properties of hardened mortar and concrete like compressive strength and workability will be determined for different mix combinations of materials and these values will be compared with the corresponding values of conventional mortar and concrete.

The present investigation has been aimed at to bring awareness amongst the practicing civil engineers regarding advantages of these new mortar and concrete mixes in terms of strength, durability, workability and economy.

PROBLEM STATEMENT

Numerous waste materials are generated from manufacturing processes, service industries and municipal solid wastes. The increasing awareness about the environment has tremendously contributed to the concerns related with disposal of the generated wastes.

Solid waste management is one of the major environmental concerns in the world. With the scarcity of space for landfilling and due to its ever increasing cost, waste utilization has become an attractive alternative to disposal.

AIM AND OBJECTIVES OF PROJECT

AIM OF PROJECT: The main aim of the project is to determine the strength properties (such as compressive strength, tensile strength, workability etc.) of mortar and concrete using waste glass powder as partial replacement for cement and fine aggregate respectively.

OBJECTIVES OF PROJECT: The main objective of this research is to study the effect of waste glass powder on the properties of mortar and concrete mixes as a partial replacement of cement and fine aggregate respectively. Other objectives include:

• To investigate the applicability of recycled glass powder in concrete mixture and mortar mixture.

• To examine the mechanical properties of the concrete with recycled glass as replacement of fine aggregate in concrete.

• To examine the mechanical properties of the mortar with recycled glass powder as replacement of cement in mortar.

JUSTIFICATION

The use of recycled glass powder in concrete and mortar not only makes it economical, but also helps in reducing disposal problems in the environment. Recycling of wastes is considered the best environmental option for solving the problems of waste disposal.

This project study overcomes the issue of the glass waste that is generated from construction and demolition activity. In order to reduce the product of glass waste, it has been suggested to reuse recycled glass waste powder to substitute a percentage of the cement and fine aggregate respectively.
