Answer all the questions given
Sila jawab semua soalan yang diberikan.

• 1.

### Konkrit adalah merupakan campuran simen, batu baur kasar/halus dan air.

• A.

True

• B.

False

A. True
Explanation
The given statement is true. Konkrit is indeed a mixture of cement, coarse/fine aggregate, and water. This combination of materials is commonly used in construction for its strength and durability.

Rate this question:

• 2.

### Nisbah 1:3:6 adalah digunakan untuk membina tiang dan rasuk.

• A.

True

• B.

False

B. False
Explanation
The given statement suggests that the ratio 1:3:6 is used for constructing columns and beams. However, this statement is false. The ratio 1:3:6 is not commonly used for constructing columns and beams. These ratios may vary depending on the specific requirements of the structure and the load it needs to bear. Therefore, the correct answer is false.

Rate this question:

• 3.

### Nisbah 1 : 1/1/2 : 3 digunakan untuk membina konkrit tegas dulu dan tangki.

• A.

True

• B.

False

A. True
Explanation
The given statement is true. The ratio 1:1/2:3 is used to construct strong concrete and tanks. This ratio indicates the proportion of cement, sand, and aggregate used in the concrete mix. A higher proportion of cement and aggregate ensures the strength and durability of the concrete, making it suitable for building structures like tanks. Therefore, the statement is correct.

Rate this question:

• 4.

### Kualiti bahan, nisbah bancuhan, penggredan batu baur dan kualiti acuan merupakan antara faktor penentu kualiti konkrit.

• A.

True

• B.

False

A. True
Explanation
The statement provided states that the quality of materials, mixing ratio, grading of aggregate, and quality of reference are among the factors that determine the quality of concrete. This implies that these factors play a crucial role in determining the overall quality of concrete. Therefore, the answer "True" is correct.

Rate this question:

• 5.

### Berkarat dan reput merupakan salah satu sifat konkrit.

• A.

True

• B.

False

B. False
Explanation
The statement is false because "berkarat dan reput" (rusty and dirty) are not concrete qualities. They are physical attributes that describe the condition or appearance of an object, but they are not inherent properties of the object itself. Concrete qualities refer to tangible characteristics that can be directly observed or measured, such as size, weight, color, or texture.

Rate this question:

• 6.

### Kukuh dan kos yang murah merupakan kelebihan utama konkrit berbanding bahan lain.

• A.

True

• B.

False

A. True
Explanation
The given statement states that affordability and strength are the main advantages of concrete compared to other materials. This implies that concrete is not only cost-effective but also durable, making it a desirable choice for construction purposes. Therefore, the statement is true.

Rate this question:

• 7.

### Empangan dan papak lantai merupakan contoh anggota struktur yang menggunakan konkrit.

• A.

True

• B.

False

B. False
Explanation
The statement says "Empangan dan papak lantai merupakan contoh anggota struktur yang menggunakan konkrit" which translates to "Dams and floor slabs are examples of structural members that use concrete." This statement is false because dams and floor slabs are actually examples of structural members that use reinforced concrete, not just concrete. The reinforcement in the form of steel bars or mesh is added to enhance the strength and durability of the structure.

Rate this question:

• 8.

### Simen ialah bahan yang dihasilkan dengan membakar campuran batu baur kapur dan tanah liat serta mempunyai sifat lekitan dan lekatan.

• A.

True

• B.

False

A. True
Explanation
The given statement states that "Simen is a material produced by burning a mixture of limestone and clay and has adhesive and cohesive properties." This statement is true because cement, or simen, is indeed produced by heating a mixture of limestone and clay at high temperatures. This process, known as calcination, results in the formation of calcium silicates, which give cement its adhesive and cohesive properties. Therefore, the correct answer is true.

Rate this question:

• 9.

### Simen portland penahan sulfat sesuai digunakan di kawasan yang kering.

• A.

True

• B.

False

B. False
Explanation
The given statement suggests that Simen portland penahan sulfat is suitable for use in dry areas. However, the correct answer is False. This means that Simen portland penahan sulfat is not suitable for use in dry areas.

Rate this question:

• 10.

### Proses basah dan kering merupakan 2 kaedah penting dalam penghasilan simen.

• A.

True

• B.

False

A. True
Explanation
The statement is true because wet and dry processes are indeed two important methods in the production of cement. The wet process involves grinding and mixing raw materials, such as limestone and clay, with water to form a slurry. This slurry is then heated in a kiln to produce clinker, which is further ground to produce cement. On the other hand, the dry process involves grinding and mixing the raw materials without the addition of water, and then feeding the dry mixture into a kiln for further processing. Both processes have their advantages and disadvantages, and the choice between them depends on various factors such as the availability of raw materials and energy efficiency.
